R is for real numbers, rational or irrational (Ex. Q represents rational numbers, so all numbers that can be represented as a fraction. N is the set of Natural Numbers. Z is the set of integers, so whole numbers, both positive and negative.

What does the weird R mean in math?

Answered Nov 29, 2017. If you mean the capital R as appears in denoting sets, then that stands for real numbers. The real number set includes all rational and irrational numbers, such as 2, , and square roots of positive numbers.

What Does E Mean In Math

The letter E can have two different meaning in math, depending on whether it’s a capital E or a lowercase e. You usually see the capital E on a calculator, where it means to raise the number that comes after it to a power of 10. For example, 1E6 would stand for 1 × 106, or 1 million. Normally, the use of E is reserved for numbers that would be too long to be displayed on the calculator screen if they were written out longhand.

Mathematicians use the lowercase e for a much more interesting purpose to denote Euler’s number. This number, like , is an irrational number, because it has a non-recurring decimal that stretches to infinity. Like an irrational person, an irrational number seems to make no sense, but the number that e denotes doesn’t have to make sense to be useful. In fact, it’s one of the most useful numbers in mathematics.

What Are Whole Numbers

Natural numbers refer to a set of positive integers and on the other hand, natural numbers along with zero form a set, referred to as whole numbers. However, zero is an undefined identity that represents a null set or no result at all.

In simple words, whole numbers are a set of numbers without fractions, , or even negative integers. It is a collection of positive integers and zero. The primary difference between natural and whole numbers is zero.

Whole Number Definition:

Whole Numbers are the set of natural numbers along with the number 0. The set of whole numbers in Mathematics is the set .This set of whole numbers is denoted by the symbol W.

Here are some facts about whole numbers, which will help you understand them better:

  • All natural numbers are whole numbers.
  • All counting numbers are whole numbers.
  • All positive integers including zero are whole numbers.
  • All whole numbers are real numbers.

List Of Letters Used In Mathematics And Science

This list is about the meanings of the letters used in mathematics, science and engineering. SI units are indicated in parentheses. For the Unicode blocksee Mathematical Alphanumeric Symbols.
This list is incomplete you can help by adding missing items.

Latin and Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities.

Some common conventions:

Natural Numbers Counting Numbers

The letter is the symbol used to represent natural numbers. Natural numbers are also known as counting numbers, and they begin with the number 1 and continue to infinity , which is represented by three dots .

The natural or counting numbers : 1, 2, 3, 4 . . . “and so on.”

Whole Numbers

The letter is the symbol used to represent whole numbers. Whole numbers are counting numbers from 0 to infinity.

The whole numbers : 0, 1, 2, 3, 4 . . .

Notice that every natural number is a whole number.


The letter is the symbol used to represent integers. An integer can be 0, a positive number to infinity, or a negative number to negative infinity.

The integers : . . . -3, -2, -1, 0, 1, 2, 3 . . .

Notice that every whole number is an integer.

Watch the following video to gain a better understanding of integers.

Rational Numbers

The letter is the symbol that is used to represent rational numbers. Rational numbers are sometimes called fractions. They are numbers that can be written as the quotient of two integers. They have decimal representations that either terminate or do not terminate but contain a repeating block of digits. Some examples are below:

Some rational numbers are graphed below.

Notice that every integer is a rational number.

Example: Real Numbers

  • Is every whole number a natural number?
  • No. The number 0 is a whole number, but it is not a natural number.

  • Is there an integer that is not a natural number?
  • Yes. Some examples are 0, 1, 2, 3, and 4.


    How To Know What The Letters Mean In Math Formulas

    What is STEM? What is Science? What does STEM stand for?

    For example, see this Wikipedia section on Newton’s laws of motion:

    Newton’s Second Law states that an applied force, $\mathbf F$, on an object equals the rate of change of its momentum, $\mathbf p$, with time. Mathematically, this is expressed as:$$\mathbf F =\frac =\frac.$$

    Based on this chart of symbols I understand they are saying $A / B = C / D$ and that $\mathrm d$ is a function and $m \mathbf v$ is the input to that function, but how do I figure out what “$\mathrm d \mathbf p$”, “$\mathrm dt$”, “$\mathrm d$”, and “$m \mathbf v$” mean? Please don’t give me the answer, but instead, pretty please tell me what method a math person would use to always know what there mean .

    I can sort of guess that $m \mathbf v$ might mean motion/velocity or something, but surely you’re not just supposed to guess at the symbols. A see formulas like this all the time and I can never find a key that explains what the letters mean. What am I missing?

    A mathematical text would define the notation it uses, either within the body of the text or in an index of symbols at the start or end of the text, unless the notation is really common. For example, a high school text would not define the symbol for ordinary addition or subtraction.

    If you are ready to see what the notation in your example means, read on. Otherwise, stop here.

    Furthermore, people cannot map the earth from smartphones without computer programmers to generate mathematical algorithms to provide this technology. If you choose to pursue a career in information technology, whether it is in security, networking, mobile applications, or geospatial technology, you will need a certain level of mathematical knowledge.

    In this lesson, you will learn how real numbers are ordered, how many categories of numbers exist, and mathematical symbolism that allows you to quickly compare or categorize numbers.

    Whole Numbers On Number Line

    The set of natural numbers and the set of whole numbers can be shown on the number line as given below. All the positive integers or the integers on the right-hand side of 0, represent the natural numbers, whereas all the positive integers along with zero, altogether represent the whole numbers. Both sets of numbers can be represented on the number line as follows:

    How Do I Construct A Real Number Line

    Here are three steps to follow to create a real number line.

  • Draw a horizontal line.
  • Choose any point on the line and label it 0. This point is called the origin.

  • Choose a convenient length. Starting at 0, mark this length off in both directions, being careful to make the lengths about the same size.
  • Now that you have created a number line, it is time see how points on a number line are defined.

    List Of Mathematical Symbols By Subject

    The following list of mathematical symbols by subject features a selection of the most common symbols used in modern mathematical notation within formulas, grouped by mathematical topic. As it is impossible to know if a complete list existing today of all symbols used in history is a representation of all ever used in history, as this would necessitate knowing if extant records are of all usages, only those symbols which occur often in mathematics or mathematics education are included. Many of the characters are standardized, for example in DIN 1302 General mathematical symbols or DIN EN ISO 80000-2 Quantities and units Part 2: Mathematical signs for science and technology.

    The following list is largely limited to non-alphanumeric characters. It is divided by areas of mathematics and grouped within sub-regions. Some symbols have a different meaning depending on the context and appear accordingly several times in the list. Further information on the symbols and their meaning can also be found in the respective linked articles.

    Where Does Euler’s Number E Come From

    THE SCUTOID: did scientists discover a new shape?

    The number represented by e was discovered by mathematician Leonard Euler as a solution to a problem posed by another mathematician, Jacob Bernoulli, 50 years earlier. Bernoulli’s problem was a financial one.

    Suppose you put $1,000 in a bank that pays 100% annual compound interest and leave it there for a year. You’ll have $2,000. Now suppose the interest rate is half that, but the bank pays it twice a year. At the end of a year, you’d have $2,250. Now suppose the bank paid only 8.33%, which is 1/12 of 100%, but paid it 12 times a year. At the end of the year, you’d have $2,613. The general equation for this progression is:

    where r is 1 and n is the payment period.

    It turns out that, as n approaches infinity, the result gets closer and closer to e, which is 2.7182818284 to 10 decimal places. This is how Euler discovered it. The maximum return you could get on an investment of $1,000 in one year would be $2,718.

    Order Of Operations Defined

    In the United States we have adopted the acronym PEMDAS whereas in Europe you may use BODMAS, and in Canada, BEMDAS or even GEMDAS as Purple Math nicely states. And you may have even heard of the fun mnemonic Please Excuse My Dear Aunt Sally.

    How to Remember the Order of Operations

    And these acronyms help us to remember which operations receive higher priority or precedence or rank. Regardless of which acronym you use, all of them apply the same convention of which operation is to be performed first. Math order of operations goes something like this:

    • Parentheses or Brackets represent any Grouping Symbol, and that means you must simplify inside them first
    • Exponents or Order represents Powers like squaring, cubing, etc.
    • Multiplication and Division
    • Addition and Subtraction

    In this lesson we are going to ensure mastery of the Order of Operations for numerical expression, with countless examples, and we are going to successfully evaluate variable expressions using substitution, which is is just another way of saying plug it in.

    Glossary Of Mathematical Symbols

    A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula. As formulas are entirely constituted with symbols of various types, many symbols are needed for expressing all mathematics.

    The most basic symbols are the , and the letters of the Latin alphabet. The decimal digits are used for representing numbers through the HinduArabic numeral system. Historically, upper-case letters were used for representing points in geometry, and lower-case letters were used for variables and constants. Letters are used for representing many other sort of mathematical objects. As the number of these sorts has dramatically increased in modern mathematics, the Greek alphabet and some Hebrew letters are also used. In mathematical formulas, the standard typeface is italic type for Latin letters and lower-case Greek letters, and upright type for upper case Greek letters. For having more symbols, other typefaces are also used, mainly boldface a },\ldots } , German fraktur a _} .

    The use of Latin and Greek letters as symbols for denoting mathematical objects is not described in this article. For such uses, see Variable and List of mathematical constants. However, some symbols that are described here have the same shape as the letter from which they are derived, such as } .

    Sets Defined By Enumeration

    A set can be described directly by enumerating all of its elements between curly brackets, as in the following two examples:

    • { is the set containing the four numbers 3, 7, 15, and 31, and nothing else.
    • =\} is the set containing a, b, and c, and nothing else .

    This is sometimes called the “roster method” for specifying a set.

    When it is desired to denote a set that contains elements from a regular sequence, an ellipses notation may be employed, as shown in the next examples:

    • { is the set of integers between 1 and 100 inclusive.
    • { is the set of natural numbers.
    • =\} is the set of all integers.

    There is no order among the elements of a set , but with the ellipses notation, we use an ordered sequence before the ellipsis as a convenient notational vehicle for explaining which elements are in a set. The first few elements of the sequence are shown, then the ellipses indicate that the simplest interpretation should be applied for continuing the sequence. Should no terminating value appear to the right of the ellipses, then the sequence is considered to be unbounded.

    In general, denotes the set of all natural numbers i . Another notation for . A subtle special case is n is equal to the empty set â ,\dots ,a_\}} denotes the set of all a .

    • } is the set of all addresses on Pine Street.
