Mathematics Vocabulary Study Guide

Understanding mathematics vocabulary is essential for students to excel in their math studies. Here are some key terms and their explanations to help you build your math vocabulary:

1. Addition

Addition is a mathematical operation that combines two or more numbers to find their total sum. For example, 2 + 3 = 5.

2. Subtraction

Subtraction is a mathematical operation that finds the difference between two numbers. For example, 5 - 3 = 2.

3. Multiplication

Multiplication is a mathematical operation that combines groups of numbers to find their total. For example, 2 x 3 = 6.

4. Division

Division is a mathematical operation that splits a number into equal groups. For example, 6 ÷ 2 = 3.

5. Fraction

A fraction represents a part of a whole or a part of a set. It consists of a numerator (the top number) and a denominator (the bottom number). For example, 1/2 represents one half of a whole.

6. Decimal

A decimal is a way of writing numbers that are not whole numbers. It includes a decimal point and digits to the right of the decimal point, representing parts of a whole number. For example, 3.5 represents three and five-tenths.

7. Area

Area is the amount of space inside a shape. It is measured in square units, such as square inches or square centimeters.

8. Perimeter

Perimeter is the distance around the edge of a shape or the total length of its sides. For example, to find the perimeter of a rectangle, you would add the lengths of all four sides.

9. Polygon

A polygon is a closed figure made up of straight lines. Common examples include triangles, squares, and pentagons.

By familiarizing yourself with these key mathematics vocabulary terms, you can confidently tackle various math problems and better understand mathematical concepts.
