math i guess
inequality-An inequality says that two values are not equal. a ≠ b says that a is not equal to b. 
input-In mathematics, input and output are terms that relate to functions.
inverse operation-Inverse operations are opposite operations that undo each other
x-axis-Horizontal axis is the x-axis on a graph. The blue number line in the figure below is the x-axis, the horizontal axis.
y-axis-the secondary or vertical axis of a system of coordinates, points along which have a value of zero for all other coordinates.
number line-In basic mathematics, a number line is a picture of a graduated straight line that serves as abstraction for real numbers, denoted by . Every point of a number line is assumed to correspond to a real number, and every real number to a point.
tape diagrams-Tape diagrams are visual models that use rectangles to represent the parts of a ratio. Since they are a visual model, drawing them requires attention to detail in the setup. In this problem David and Jason have numbers of marbles in a ratio of 2:3.
horizontal axis-the principal or horizontal axis of a system of coordinates, points along which have a value of zero for all other coordinates. !
constrant-In mathematics, a constraint is a condition of an optimization problem that the solution must satisfy.
output-In mathematics, input and output are terms that relate to functions. Both the input and output of a function are variables,
algebraic equation-an equation obtained by equating to zero a sum of a finite number of terms each one of which is a product of positive integral powers (including the zero power) of the variables.
algebraic expression-An algebraic expression is a mathematical phrase that can contain ordinary numbers, variables (like x or y) and operators (like add,subtract,multiply, and divide).
dependent variable-A dependent variable is a variable whose value depends upon independent variable s.
independent variable-An independent variable is a variable that represents a quantity that is being manipulated in an experiment.
equivalent-of the same value
equivalent ratio-two ratios that have the same value
line graph-A line graph (also called a line chart or run chart) is a simple but powerful tool and is generally used to show changes over time.
operation-Tape diagrams are visual models that use rectangles to represent the parts of a ratio.
like terms-"Like terms" are terms whose variables (and their exponents such as the 2 in x2) are the same
tape diagram-Tape diagrams are visual models that use rectangles to represent the parts of a ratio.
solve-To solve something is to find a solution, like figuring out the answer to a complex riddle. The verb solve is often used in mathematics, and it means to answer a math problem.
variable- variable is a quantity that may change within the context of a mathematical problem or experiment
