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

What is a variable in algebra?

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

• Something that is unknown in algebra, usually represented by a letter

• A list of numbers in order

What are like terms in algebra?

• Terms whose variables are the same

• Terms next to each other in a sequence

• Terms that are equal to each other

• Terms that have different values in the same problem

What is substitution in algebra?

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

• A general rule for a relationship between quantities

• Putting numbers where letters are

What is a formula in algebra?

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