What is the order of operations in mathematics?

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).

What does it mean to simplify an expression?

Back

To simplify an expression means to reduce it to its simplest form by performing operations and combining like terms.

Front

What is a fraction?

Back

A fraction represents a part of a whole and is written as 'a/b', where 'a' is the numerator (the number of parts) and 'b' is the denominator (the total number of equal parts).

Front

How do you convert a decimal to a fraction?

Back

To convert a decimal to a fraction, write the decimal over 1, multiply the numerator and denominator by 10 for each digit after the decimal point, and then simplify.

Front

What is the area of a rectangle?

Back

The area of a rectangle is calculated by multiplying its length by its width (Area = length × width).

Front

What is a coordinate grid?

Back

A coordinate grid is a two-dimensional plane formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis), used to locate points using ordered pairs (x, y).

Front

What does it mean for points to be equidistant?

Back

Points are equidistant if they are the same distance from a specific point or line.

Front

How do you find the distance between two points on a coordinate grid?

Back

The distance between two points (x1, y1) and (x2, y2) can be found using the distance formula: Distance = √((x2 - x1)² + (y2 - y1)²).

Front

What is a unit cube?

Back

A unit cube is a cube with a side length of one unit, used to measure volume.

Front

How do you calculate the volume of a rectangular prism?

Back

The volume of a rectangular prism is calculated by multiplying its length, width, and height (Volume = length × width × height).
