Term | Definition |
Power | A number that represents repeated multiplication
Example: 10^5 or 10 to the power of 5 |
Base | The number that is used as a factor.
Example: 1 |
Exponent | Tells how many times the factor is used.
Example: 2^6 |
Expression | Consists of a combination of numbers and an operation.
Example: 2^2 + 2 |
Term | A part of an expression that is separated by a plus or a minus sign.
Example: 1 + 2 |
Super Scripted Numbers | A exponent
Example: ^5 |
Factor | Numbers you can multiply to get another number. |
Order Of Operations | The rules on how to solve an expression.
Example: PEMDAS |
Numerical Expression | A mathematical phrase that has only numbers and one or more only operation symbols.
Example: 4+3=7 |
Algebra | Uses letters or other symbols in place of unknown values, can be used in a expression.
Example: 2+y=7 |
Algebraic Expression | A mathematical phrase that contains ordinary numbers, and variables.
Example: 2+7=y |
Variable | A number that we have to figure out in an algebraic expression.
Example: 2+y=7 Variable=y |
Equation | Says two things are equal, and has an "= "sign.
Example: (12+3)=(14+1) |
Properties | Statements that are true for any number.
Example: 6+10 or 10+6 |
Commutative Properties | Allows you to change the order in which two numbers are added or multiplied without changing the product or sum.
Example: a+b or b+a, ab = ba |
Associative Properties | Allows you to change the grouping of two numbers that are being multiplied or added without changing the sum or the product.
Example: (b+c) = (a+b), a(bc) or (ab)c |
Identity Properties | Allows you to add 0 to an number and not change its sum and allows you to do the same with multiplying but with 1 and the same with division.
Example: 22+0, 22 x 1, and 22 / 1 |
Equivalent Expressions | Expressions that have the same sum but are switched around.
Example: 6 x 10 or 10 x 6 |
Distributive Property | Multiply a group of numbers or separately.
Example: 2(7*8) or 2*7 + 2*8 |
Factor the Expression | When numeric or algebraic expression are written as a product of their factors.
Example: 12 + 8 |
Coefficient | A number used to multiply a variable.
Example: 22x |
Constant | A number thats on its own. Example: 4x+7 |
Like Terms | To variable that are the same. Example: 2x+5x=7x |
