Order of Operations

Put your thinking caps on and solve these expressions:

1.   2 + 5 x 3
2.   10 - 3 x 3
3.   3 x 8 - 7 x 2
4.   9 + 9 ➗ 3

Did you get the following answers?

1. 17   2. 1   3. 10   4. 12

These same questions sure had us thinking earlier this week! 

To help us all arrive at the same answer, we've added a new skill to our Math arsenal: PEDMAS!
The acronym PEDMAS helps us remember the order of operations 
when we are evaluating a Math expression or equation.

Today in class we practiced our skills by working in groups at the white boards.
Using four 4s, we used the order of operations to create equations that would equal each number from 0 to 10.
For example: 
0 = 4 - 4 + 4 - 4   
1 = 4 + 4  4 - 4 
and so on...



We sure had to think hard. This is not as easy as it sounds!
