Algebraic Expression parts
| Question | Answer |
|---|---|
| Algebraic Expressions | A collection of numbers, variables, and operators (with NO equals sign), packaged into a mathematical phrase. |
| Substitute | To replace a variable for a specific value. |
| Term | Each group of variables and numbers, separated by operators |
| Coefficient | The numerical factor of a term. |
| Variable | an unknown part of an equation, represented by a letter |
| Constant | A term that does not contain a variable. |
| Algebraic Expressions | 2a+5 is called________ |
| Variable | The a in 2a is called______ |
| coefficient | The 2 in 2a is called________ |
| Term | 2a or x/6 or 7 or x These are all called ________ |
| Constant | The 5 in 2a+5 is called_______ |
| Equation | two things are equal. |
| Evaluate | To calculate the value of. |
| Operation/ operator | can be either addition, subtraction, division, or multiplication. |
| positive number | A number that is greater than 0 |
| negative number | A number that is less than 0 |
| numerical expression | a collection of numbers and mathematical operators |
| isolate | get the variable alone by performing inverse operations on both sides of the equation until it stands by itself. |
| like terms | Terms with the same variable raised to the same power |
| simplify | the most compact or efficient manner, without changing the value of the expression. |
| solution | is any value of the variable that makes the equation true. |
| inverse operations | The operation that reverses the effect of another operation. |
