So PEMDAS is order of operations basicly.
P=Parenthesis
E=Exponets
M=Multiplication
D=Division
A=Addition
S=Subtraction
For example: 2x4+(9x9)-1
When solving order of operations you ALWAYS start with the problem in the parentheses.
(9x9)=81
Now multiplication comes next so, 2x4=8
Then addition, 8+81=88
Lastly subtraction, 88-1=81
PEMDAS stands for:
P - Parentheses
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
here is a very easy example
56 + 41 x 14 - 12
the multiplication would come first.
= 56 + 574 - 12
then addition.
= 630 - 12
and for the final step we subtract.
= 618!
We get the final answer of 618!
i hope i helped ;)
