Question

What is PEMDAS??? Like the meaning and i need an example too.. ._.

Answer 1

Pemdas? OK so how I would remember it by is "Please Excuse My Dear Aunt Sally"     
So.. Parenthesis, Exponent(s), Multiplication, Division, Addition, Subtraction..
Example~~~~~
($3^2}$ + 4) ×12÷4 - 1= ? so first do parenthesis and then the exponents then add it to 4 and the divide 12 and 4 and then subtract 1 which is 2.. Then after take two and 13 and multiply which is 26~
Hope this helps! :) 

Answer 2

Parenthesis exponent multiplication division addition and subtraction 

EX--- ($1^{1}$- 0) + 23*2+?
