What is division?

Back

Division is the process of splitting a number into equal parts. For example, 12 ÷ 4 means dividing 12 into 4 equal parts, which equals 3.

What is the order of operations in math?

Back

The order of operations is a set of rules that determines the sequence in which calculations are performed. The acronym PEMDAS helps remember the order: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

How do you simplify an expression?

Back

To simplify an expression, perform the operations in the correct order and combine like terms. For example, in 8 × 4 + 9 ÷ 3 - (4 + 3), first calculate the multiplication and division, then perform addition and subtraction.

What are coordinates in a Cartesian plane?

Back

Coordinates are a set of values that show an exact position on a Cartesian plane, represented as (x, y). The first number (x) indicates the horizontal position, and the second number (y) indicates the vertical position.

How do you locate a point on a graph?

Back

To locate a point on a graph, start at the origin (0, 0). Move horizontally to the x-coordinate and then vertically to the y-coordinate. For example, to locate (3, 2), move 3 units right and 2 units up.

Front

What is a fraction?

Back

A fraction represents a part of a whole and consists of a numerator (top number) and a denominator (bottom number). For example, in 1/2, 1 is the numerator and 2 is the denominator.

Front

How do you multiply fractions?

Back

To multiply fractions, multiply the numerators together and the denominators together. For example, (2/3) × (3/4) = (2 × 3) / (3 × 4) = 6/12, which simplifies to 1/2.

Front

What is a mixed number?

Back

A mixed number is a whole number combined with a fraction. For example, 2 1/2 means 2 whole parts and 1/2 of another part.

Front

How do you convert an improper fraction to a mixed number?

Back

To convert an improper fraction to a mixed number, divide the numerator by the denominator. The quotient is the whole number, and the remainder becomes the numerator of the fraction.
