## 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 … Continue reading "Multiplicative 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 … Continue reading "Additive Inverse"

## 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, … Continue reading "Equivalent Fractions"

## 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. … Continue reading "Least Common Denominator"

## 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 × … Continue reading "Expanded Notation"
