How are the quadrants in a graph set up?

Start top right and move counter clockwise.

Coefficient

a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4x y).

Degree

The squared or cubed. In an equation, the biggest degree is the one that needs to be identified.

Convex

No dents or indentations in the shape.

Concave

There are dents or indentations in the shape.

Dependent Variable

a variable (often denoted by y ) whose value depends on that of another.

Independent Variable

a variable (often denoted by x ) whose variation does not depend on that of another.

Commutative property

A math rule that says that the order in which we multiply numbers does not change the product

Distributive property

When you multiply a factor by two addends, you can first multiply the factor with each addend, and then add the sum.

Associative property

a math rule that says that the way in which factors are grouped in a multiplication problem does not change the product.

Triangular prism vs pyramid

With a pyramid, all four triangles are the same size. Prisms have sets of two matching triangles with a rectangular base.

10^0 equals

1

Mean

average or norm. Add all the values and divide by the amount of values.

Median

Middle of all the numbers placed in order.

Mode

Most frequent value.

Range

Difference between the highest and lowest number.

Prime factorization

breaking the number down to prime numbers that when multiplied equal the number. Think of break aparts.

Acute

less than 90 degrees

Obtuse

greater than 90 degrees but less than 180 degrees

Congruent

Two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.

Variable

a quantity that may change within the context of a mathematical problem or experiment. Typically, we use a single letter to represent a variable. The letters x, y, and z are common generic symbols used for variables.

Terms

In the expression, 3a + 8, 3a and 8 are terms.

algebraic expression vs equation

An expression is a number, a variable, or a combination of numbers and variables and operation symbols. An equation is made up of two expressions connected by an equal sign.

Commutative property of multiplication

AxB=BxA

0.7 is 1/1,000 of what number?

0.7 x 1,000 = 700

monomial

one term (3x)

binomial

two terms (3x + 2)

trinomial

three terms (3x + 2z + 1y)
