|---|
| absolute value | a numbers distance from zero on the number lline |
| aglebraic expression | an expression that contains at least one variable |
| conjecture | a conclusion you reach by inductive reasoning |
| counter example | an example that proves a statement false |
| coordinate plane | a plane formed by two real number lines called axis that intersect at a right angle |
| evaluate | to find the value of an expression by replacing variables with numbers |
| inductive reasoning | making conclusions based on patterns you observe |
| integers | whole numbers and their opposites {...-3, -2, -1, 0, 1, 2, 3,...} |
| opposites | two numbers that have the same absolute value (distance from zero) but opposite signs (Positive and Negative) |
