Today we discussed variables and expressions.
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 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)
6
For more practice
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
Enjoy...Ms. Gillen
