Front

What is the difference between mean, median, and mode?

Back

Mean is the average of a set of numbers, median is the middle value when numbers are arranged in order, and mode is the number that appears most frequently in a set.

How do you solve a linear equation?

Back

To solve a linear equation, isolate the variable on one side of the equation using inverse operations (addition, subtraction, multiplication, division) until the variable is alone.

Front

What is the distributive property?

Back

The distributive property states that a(b + c) = ab + ac. It allows you to multiply a single term by two or more terms inside a set of parentheses.

Front

What is the difference between perimeter and area?

Back

Perimeter is the total distance around a shape, while area is the amount of space inside a shape.

Front

Define an integer.
