Definition Difference is the result of subtracting one number from another. How much one number differs from another. More Examples Here are more examples about difference: Numbers Difference Reason 7 and 5 2 7 – 5 = 2 4 and 9 5 9 – 4 = 5 11 and 8 3 11 – 8 =

Multiplicative Inverse

Multiplicative Inverse is Another name for Reciprocal. What you multiply by a number to get 1 In other words: When we multiply a number by its “Multiplicative Inverse” we get 1. But not when the number is 0 because 1/0 is undefined! More Examples of Multiplicative Inverse Number Multiplicative inverse 2 1/2 3 1/3 5

Additive Inverse

Definition of Additive Inverse The additive inverse of a number is another number you add to a number to create the sum of zero. In other words, additive inverse of x is another number, for examle y, as long as the sum of x + y equals zero. The additive inverse of x is equal

Equivalent Fractions

Equivalent Fractions have the same value, even though they may look different. These fractions are really the same: Why are they the same? Because when you multiply or divide both the top and bottom by the same number, the fraction keeps it’s value. The rule to remember is: “Change the bottom using multiply or divide,

Least Common Denominator

What is a Denominator? The denominator is the bottom number in a fraction. It shows how many equal parts the item is divided into Common Denominator? When the denominators of 2 or more fractions are the same, they have Common Denominators. Finding a Common Denominator One simple answer is to multiply the current denominators together.

Mixed Fractions

Mixed Fraction is also known as Mixed Number A Mixed Fraction is a whole number and a proper fraction combined. Each example is made up of a whole number and a proper fraction together. That is why it is called a mixed fraction or mixed number. 3 Types of Fractions There are 3 types of

Equal, Greater, or Less Than

As well as the familiar equals sign (=) it is also very useful to show if something is not equal to (≠) greater than (>) or less than (<) Equality and Inequality Definition In mathematics, equality is a relationship between 2 quantities or more (generally 2 mathematical expressions) asserting that the expressions represent the same

Expanded Notation

Definition Expanded Notation is about Writing a number to show the value of each digit. Expanded Notation is shown as a sum of each digit multiplied by its matching place value (ones, tens, hundreds, etc.) Examples 1,234 = 1 × 1,000 + 2 × 100 + 3 × 10 + 4 × 1 98,765 = 9 ×

Rational Function

Definition Rational Function is A function that is the ratio of 2 polynomials. It is Rational because one polynomial is divided by the other polynomial, like a ratio. (Note: the denominator cannot be zero.) Examples Learn More FOIL Method Counting Numbers Difference Multiplicative Inverse Definitions Index

FOIL Method

FOIL Method is a handy way to remember how to multiply 2 binomials. Definition FOIL stands for “First, Outer, Inner, Last“ F O I L First Outer Inner Last It is the sum of: multiplying the First terms, multiplying the Outer terms, multiplying the Inner terms, and multiplying the Last terms. Examples (a+b)(c+d) = ac + ad +
