What Is The Median
The median is another form of an average. It usually represents the middle number in a given sequence of numbers when its ordered by rank. When the quiz scores are listed from lowest to highest: 30, 56, 65, 70, 84, 90, 90, 91, 92, or highest to lowest: 92, 91, 90, 90, 84, 70, 65, 56, 30, we can see that the median, or middle, score is 84.

+ Addition Plus Positive
The addition symbol + is usually used to indicate that two or more numbers should be added together, for example, 2 + 2.
The + symbol can also be used to indicate a positive number although this is less common, for example, +2. Our page on Positive and Negative Numbers explains that a number without a sign is considered to be positive, so the plus is not usually necessary.

What Does The 3 Mean In Math
In mathematics, the expression 3! is read as three factorial and is really a shorthand way to denote the multiplication of several consecutive whole numbers. Since there are many places throughout mathematics and statistics where we need to multiply numbers together, the factorial is quite useful.
A Measure Of Central Tendency
In statistics, the mean is one of the three measures of central tendency, which are single numbers that try to pinpoint the central location within a data set. The mean, or average, is used most commonly, but it is important to differentiate it from the two other measures: median and mode. The median is the middle number when the numbers are listed in ascending order, while the mode is the most frequently occurring number.

What Is The Mean
When someone asks for the average of a group of numbers, theyre most likely asking for the arithmetic mean . An arithmetic mean is calculated by adding several quantities together and dividing the sum by the number of quantities. For our example, we need to add the nine quiz scores together and then divide the sum by nine. So, the rounded average, or mean, score is 74.
How To Use Math And Maths
The only difference between math and maths is where theyre used. Math is the preferred term in the United States and Canada. Maths is the preferred term in the United Kingdom, Ireland, Australia, and other English-speaking places.
Theres no real logical explanation as to why math became preferred in some places while maths was elsewhere. The usual argument goes that mathematics is plural because it ends in an -s, so maths should be its abbreviation. The problem is that, while it ends in an s, mathematics is a mass noun and usually takes a singular verb .
Both of these words date back to the turn of the 20th century. There are examples of math in writings from the 1840s, and of maths from the 1910s.

Understanding The And & Or Probabilities:
- For instance, what is the probability of if we take out a card from its deck and it must be red AND face card?
- As per the meaning of the term AND, we need to look at the joint probability of such a card which satisfies both conditions of the outcome from this sample.
- There are only six possible cards here which Jack, Queen, and a King of Hearts and diamonds.
- Using formula, P = 6/52 = 11.5% approx.
- Now, what if the same question asked to take out a card that has Red OR a face card?
- Now, the meaning has changed completely.
- We can pick any card, whether its red, a face card, or both red and a face.
- This gives us twenty-six cards in total, which are red, which already include the face card in themselves, and six cards as both.
- We now have thirty-two such cards, which give us P = 32/ 52 deck has fifty-two cards in total, = 61.5% approx.
- See how changing just one word AND to OR changed the answer by so much.
PS In the OR problem, we do not add twelve face cards to twenty-six red cards because we already have six face cards that are red as well.
If one is not careful, he will get 38 cards instead of 32.
Other Differences Between British And American English
In some cases, British and American English use different words for the same concept. For example, American English speakers use the words truck, shopping cart, and sweater British English speakers say lorry, trolley, and jumper to mean the same things.
In still other cases, British and American English words differ by just one letter, as in the case of math and maths. British English includes U in the spelling of French-derived words, such as colour or favourite, which American English omits.
This also happens with the words sport and sports. In American English, youd say, I enjoy playing sports, and I also like watching sports. In British English, this sentence would be I enjoy playing sport, and I also like watching sport. This time, its American English that likes the s!

What Does Difference Mean In Math
In mathematics the difference is the result of subtracting one number from another, and represents the operation of removing objects from a collection. Mathematicians use the term “difference,” because it shows by how much the two numbers in the subtraction problem differ.
A basic subtraction problem is made up of three parts: the minuend, the subtrahend and the difference. The minuend is the number which appears first in the problem. This is the number which is being subtracted from. The subtrahend appears second, and is the amount being subtracted from the minuend. The difference appears last, after the equals sign, and is the amount of space between the minuend and subtrahend.
If the minuend is greater than the subtrahend, then the difference is always positive. If the minuend is less than the subtrahend, then the difference is always negative. In the order of operations, differences are the last things calculated, along with sums. Therefore, parentheses are necessary to calculate a difference before an exponent, product or quotient.
For subtracting large numbers by hand, use partial differences. These rely on the subtraction of digits in certain positions, rather than the whole number. For example, a partial difference of 753 – 491 is 700 – 400.
What Does Excess Per Claim Mean
An excess is an amount that you pay yourself when you make an insurance claim. For example, if your car is insured against accident damage and you have a minor accident that requires the replacement of a door panel to the value of R20 000, you may have to pay the first R2 500, and your insurer will pay the rest.

Why Does Insurance Have Excess
The main reason why insurers apply an excess is so they can eliminate most of, or if not all, of the minor or small claims. The cost to the insurer for the dealing with minor or small claims would only cover the administration charges therefore, they add an excess to the policy to avoid such minor claims.
Or * Or Multiplication
These symbols have the same meaning commonly × is used to mean multiplication when handwritten or used on a calculator 2 × 2, for example.
The symbol * is used in spreadsheets and other computer applications to indicate a multiplication, although * does have other more complex meanings in mathematics.
Less commonly, multiplication may also be symbolised by a dot . or indeed by no symbol at all. For example, if you see a number written outside brackets with no operator , then it should be multiplied by the contents of the brackets: 2 is the same as 2×.

What Does And Mean In Math
Mathematics is a wonderful subject and has its vocabulary and uses many English words like AND, OR, Equal to, Union, and nor, to name a few.
AND & OR are the two most confusing aspects for many students because they dont understand whether they mean addition or multiplication.
The problem increases when we study these keywords in the probability chapter, where both these become critical.
We must understand one thing that these both are operations and not simply the signs like multiplying or dividing.
What Does AND Mean in Math?
In probability, the distinction is clear, and in simple math logic symbol, + means AND.
- AND needs both conditions to be true to be valid true means satisfying the conditions.
- OR is mostly okay with anyone or both the conditions getting true for it takes place.

Notation Language And Rigor
Most of the mathematical notation in use today was not invented until the 16th century. Before that, mathematics was written out in words, limiting mathematical discovery.Euler was responsible for many of the notations in use today. Modern notation makes mathematics much easier for the professional, but beginners often find it daunting. According to Barbara Oakley, this can be attributed to the fact that mathematical ideas are both more abstract and more encrypted than those of natural language. Unlike natural language, where people can often equate a word with the physical object it corresponds to, mathematical symbols are abstract, lacking any physical analog. Mathematical symbols are also more highly encrypted than regular words, meaning a single symbol can encode a number of different operations or ideas.
