Note that “per”, in “Division”, means “divided by”, as in “I drove 90 miles on three gallons of gas, so I got 30 miles per gallon”. Also, “a” sometimes means “divided by”, as in “When I tanked up, I paid $12.36 for three gallons, so the gas was $4.12 a gallon”.
Warning: The “less than” construction, in “Subtraction”, is backwards in the English from what it is in the math. If you need, for instance, to translate “1.5 less than x“, the temptation is to write “1.5 x“. Do not do this!
You can see how this is wrong by using this construction in a “real world” situation: Consider the statement, “He makes $1.50 an hour less than me.” You do not figure his wage by subtracting your wage from $1.50. Instead, you subtract $1.50 from your wage. So remember: the “less than” construction is backwards.
Also note that order is important in the “quotient/ratio of” and “difference between/of” constructions. If a problems says “the ratio of x and y“, it means “x divided by y“, not “y divided by x“. If the problem says “the difference of x and y“, it means “x y“, not “y x“.
You’ll be expected to know that a “dozen” is twelve you may be expected to know that a “score” is twenty. You’ll be expected to know the number of days in a year, the number of hours in a day, and other basic units of measure.

Again the factor change in a quantity is the multiplier that takes you from the initial value of some quantity to the final or changed value of that quantity. Notice that the factor change in a quantity can easily be calculated by taking the final quantity and dividing it by the initial quantity.

What Is Number Line
In math, a number line can be defined as a straight line with numbers placed at equal intervals or segments along its length.A number line can be extended infinitely in any direction and is usually represented horizontally.
The numbers on the number line increase as one moves from left to right and decrease on moving from right to left.
Here, fractions and decimals have been represented on the number line.
A number line can also be used to represent both positive and negative integers as well.
Writing numbers on a number line makes comparing numbers easier. Numbers on the left are smaller than the numbers on the right of the number line.
|Fun Facts A blank number line was originally proposed as a visual model or diagram for solving addition and subtraction operations. An empty or blank number line is a visual diagram of a number line with no numbers or markers and is essentially used for solving word problems.|

How Do You Know When To Divide Or Multiply In A Word Problem

The Mathematical Definition Of Unity
- Ph.D., Business Administration, Richard Ivey School of Business
- M.A., Economics, University of Rochester
- B.A., Economics and Political Science, University of Western Ontario
The word unity carries many meanings in the English language, but it is perhaps best known for its most simple and straightforward definition, which is “the state of being one oneness.” While the word carries its own unique meaning in the field of mathematics, the unique use does not stray too far, at least symbolically, from this definition. In fact, in mathematics, unity is simply a synonym for the number “one” , the integer between the integers zero and two .
The number one represents a single entity and it is our unit of counting. It is the first non-zero number of our natural numbers, which are those numbers used for counting and ordering, and the first of our positive integers or whole numbers. The number 1 is also the first odd number of the natural numbers.
The number one actually goes by several names, unity being just one of them. The number 1 is also known as unit, identity, and multiplicative identity.

What is percentage increase or decrease?
Definition: Percent increase and percent decrease are measures of percent change, which is the extent to which a variable gains or loses intensity, magnitude, extent, or value. The figures are arrived at by comparing the initial and final quantities according to a specific formula.
What word means to decrease?
Some common synonyms of decrease are abate, diminish, dwindle, lessen, and reduce. While all these words mean to grow or make less, decrease suggests a progressive decline in size, amount, numbers, or intensity. When would abate be a good substitute for decrease?
How do you calculate decline?
The decline is generally in share price, revenues, expenses, earnings, earnings per share, assets, liabilities, shareholders equity, and cash flow, and is calculated using the growth rate formula, which is the product of the final value less the starting value divided by the starting value multiplied by 100.
+ 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.

Where Is Percentage Increase Useful
Percentage increase is useful when you want to analyse how a value has changed with time. Although percentage increase is very similar to absolute increase, the former is more useful when comparing multiple data sets. For example, a change from 1 to 51 and from 50 to 100 both have an absolute change of 50, but the percentage increase for the first is 5000%, while for the second it is 100%, so the first change grew a lot more. This is why percentage increase is the most common way of measuring growth.
Percentage Increase Between Two Numbers
As we discussed the concept of percentage increase, let us understand how to find the increase between two numbers in percent form.

Mathematically, we can write the formula for the same as,
Percentage Increase Between Numbers = Increase in Number ÷ Original Number × 100
Important Notes on Percentage Increase
- The percentage increase is the difference between the final value and the initial value, expressed in the form of a percentage.
- The percentage increase formula is derived and expressed as Percentage Increase = × 100
- If the percentage change is positive, then it is the percentage increase and if the percentage change is negative, it is a percentage decrease.
