Who put those letters in my math problem?!

Don't panic!

Interpreting Expressions with Parentheses

This can be read as

"four groups of 5 + 3y"

On a sheet of paper, write out

four groups of 5 + 37

It should look like this:

5 + 3y

5 + 3y

5 + 3y

5 + 3y

Let's see if we can write this a little bit simpler.

• 5 + 3y

  5 + 3y

  5 + 3y

  5 + 3y

• 20 + 12y

Thinking through the answer​

Why is there a subtraction sign in the answer?

If there is math left, shouldn't we solve it?

​

​

10x and 15 don't play nice with each other because one has a variable (x) and the other is a constant (plain number).

8 groups of 3 + 2x

• That's a lot of groups!

• What if you're feeling lazy and don't want to write out 8 groups?

• You have another option!

Invisible Multiplication

• Don't forget about the invisible multiplication between the 8 and the (
