I love this!
Ok so PEMDAS stands for
Please : Parentheses
Excuse : Exponents
My : Multiplication
Dear : Division
Aunt : Addition
Sally : Subtraction
and Lydia, I think I may have learned Pretty Please too and the second P just stands for Powers instead of E for Exponents.
Another thing is that I have my kids circle the MD and AS because really those two go together and you do all the M and D from left to right and you do all the A and S from left to right. Its not that you do all the multiplying and then all the dividing.
LA: its interesting because you did the dividing all at once 12/2 and 4/8 and go 1/2 which worked out in the end anyway even though that is not the way I would have done it.
Here is my work:
72 – 4 + 12 ÷ 2 x 4 ÷ (5 + 3)
72 – 4 + 12 ÷ 2 x 4 ÷ 8
49 – 4 + 12 ÷ 2 x 4 ÷ 8
49 – 4 + 6 x 4 ÷ 8
49 – 4 +24 ÷ 8
49 – 4 + 3
45 + 3
48
We draw an upside down triangle around ours when we are done for those visual folks and we circle each step when we are going to do it.
So yeah, unfortunately Papa Steve might lose some points in my class.
So if you want to try again..here is another one:
23 + 10 ÷ 5 x (32 – 3) + 7 – 8
*Hint: follow PEMDAS inside the parentheses.
