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. |
