Term | Definition |
algebra | the branch of mathematics that involves expressions with variables |
algebraic expression | a combination of variables, numbers, and at least one operation |
arithmetic sequence | a sequence in which each term is found by adding the same number |
base | in a power, the number used as a factor |
coefficient | the numerical factor of a term that contains a variable |
constant | a term that does not contain a variable |
cubed | the product in which in a number is a factor three times |
defining the variable | choosing a variable to represent an unknown value in a problem, and using it to write an expression or equation so solve the problem |
equation | a mathematical sentence that contains an equal sign |
equivalent expressions | expressions that have the same value |
evaluate | to find the value of an expression |
exponent | in a power, the number that tells how many times the base is used as a factor |
exponential form | numbers written with exponents |
factors | two or more numbers that are multiplied together to form a product |
geometric sequence | a sequence in which each term can be found by multiplying the previous term by the same number |
gram | a unit of mass in the metric system equivalent to 0.001 kilogram |
kilogram | the base unit of mass in the metric system equivalent to 1,000 grams |
liter | the base unit of capacity in the metric system, a little more than a quart |
meter | the base unit of length in the metric system |
metric system | a base-ten system of measurement using the base units: meter for length, kilogram for mass, and liter for capacity |
numerical expression | a combination of numbers and operations |
order of operations | the rules to follow when more than one operation is used in a numerical expression |
powers | numbers expressed using exponents |
properties | statements that are true for any number or variable |
scientific notation | a number written as a product of a number that is at least 1 but less than 10, and a power of ten |
sequence | a list of numbers in a certain order |
solution | a value for the variable that makes an equation true |
solving an equation | the process of finding a solution to an equation |
squared | a number multiplied by itself |
standard form | numbers written without exponents |
term | a number, a variable, or a product or quotient of numbers and variables/ each number in a sequence |
variable | a placeholder, usually a letter, used to represent an unspecified value in mathematical expressions or sentences |
