A method of estimating in order to make working with a number easier.
rounding
A reciprocal of a number is that number which, when multiplied by the original number, equals 1. It is
the same as the multiplicative inverse.
reciprocal
Measures one quantity in relation to another quantity.
ratio
A fraction where the number in the numerator is more than the number in the denominator.
improper fraction
A method used to prove that a proportion is true.
cross multiplying
A value that is known and unchanging.
constant
The y-value of the point at which a line intersects with the y-axis.
y-intercept
A mathematical principle used to multiply one term by multiple terms. This principle is employed when
there are parentheses around multiple terms, which are in turn multiplied by a single term.
distributive property
The four sections of the coordinate plane, separated and defined by the x-axis and y-axis.
quadrants
When a variable is substituted by its known value in an algebraic expression or equation.
the substitution method

, The value that describes the direction and steepness of a line drawn on the coordinate plane. It is
measured by 'rise over run.' Rise/Run = (the change in y value) / (the change in x value) = (y2 - y1)/(x2 -
x1)
slope
A string of numbers connected by elementary operations.
arithmetic expression
A number by which a variable is multiplied. This number is written in front of the variable(s).
coefficients
Any equation that contains variables, constants, or mathematical operations.
algebraic equation
Addition, subtraction, multiplication, and division.
elementary operation
The vertical line that passes through the origin on a coordinate plane.
y-axis
Two mathematical expressions separated by the equals sign, =. The two expressions on either side of
the equals sign hold the same value as one another.
equation
The point (0,0) on a coordinate plane, which is where the x-axis and y-axis intersect.
origin
If you perform equivalent operations to both side of an equation, the result will always be an equivalent
equation.
the principle of equality
A string of terms that are connected by division, addition, and subtraction operations.
algebraic expression
A symbol that represents a mathematical value.
variable
A number or numerical worth.
value
The largest exponent in an expression.
