- 3. Multiplying each term in a sum or difference by a common factor does not change the value of the expression. For any numbers a, b, and c, a(b + c) = ab + ac. Equation: A mathematical statement that uses an equal sign (=) to show that two expressions have the same value.
- 4. To find the value of an expression.
- 5. Numbers that are less than 0. They are located to the left of 0 on a horizontal number line and below 0 on a vertical number line. Opposite numbers: Numbers that are the same distance from 0 on a number line but in opposite directions. Opposite numbers have the same numeral, but opposite signs. The opposite of a number is also called the additive inverse of that number.
