Front 6

inequality

Back 6

is a relation that holds between two values when they are different

Front 7

balance

Back 7

When both sides have the same quantity or mass

Front 8

inverse operation

Back 8

opposite operations that undo each other.

Front 9

variable

Back 9

In mathematical terms, the dependent variable y represents the value of a function of x. To simplify formulas, it is often useful to use the same symbol for the dependentvariable y and the function mapping x onto y.

Front 10

coefficient

Back 10

A number or symbol multiplied with a variable or an unknown quantity in an algebraic term. For example, 4 is the coefficient in the term 4x, and x is the coefficient in x(a + b). A numerical measure of a physical or chemical property that is constant for a system under specified conditions.

Front 11

term

Back 11

In Algebra a term is either a single number or variable, or numbers and variables multiplied together. Terms are separated by + or − signs. See: Variable. Algebra - Definitions.

Front 12

equation

Back 12

A written statement indicating the equality of two expressions. It consists of a sequence of symbols that is split into left and right sides joined by an equal sign. For example, 2 + 3 + 5 = 10 is anequation.

Front 13

expression

Back 13

An algebraic expression is a mathematicalphrase that can contain ordinary numbers, variables (like x or y) and operators (like add,subtract,multiply, and divide).

Front 14

slope

Back 14

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. Slope is often denoted by the letter m. The direction of a line is either increasing, decreasing, horizontal or vertical.
