Key concepts students will learn:

  • When evaluating an expression, you are finding the value of the expression once you work through it.

  • When you have a number next to a variable, such as 3m, that means they are being multiplied, so 3m means 3 times m.

  • When evaluating expressions, use the order of operations, also known as PEMDAS, to know what order to perform the operations.
