What is algebra?

• The study of lines, angles, and the size and position of 2D and 3D shapes

• The unit of measurement used for angles

• The part of mathematics that uses letters or symbols in the place of unknown values or quantities

• A group of numbers, symbols, and operators grouped together that show the value of something

What is the goal of algebra?

• To find the difference between terms

• To measure angles

• To solve equations

• To study the relationship between quantities
