Today we discussed

Forget what those words mean?Look them up!

Variables were those letters we were using in class today. They always represent a number. Sometimes we have to solve an equation to figure them out. Sometimes we are given a value for them and can just plug it in - just like we did today. Remember - when there is

Here is an example:

20 - (3+4) * 2 (I plugged in the numbers for each variable)

20 - 7*2 (Parenthesis first)

20 - 14 (I multiplied 7 and 2)

6

1) I assigned 2 tasks on studyladder.

2) Practice!! Keep trying until you get at least 10 correct

3) Quiz - try to win a million

4) Play this hockey game

**no equal sign we call it an expression.**Here is an example:

**p - (z + 4) * 2 --> if p = 20 and z = 3**20 - (3+4) * 2 (I plugged in the numbers for each variable)

20 - 7*2 (Parenthesis first)

20 - 14 (I multiplied 7 and 2)
