How do you use PEMDAS to simplify #(5+22)*(35-27)+6^2#?
Rather than blindly following PEDMAS or PEMDAS or BODMAS etc, which often leads to wrong answers, work in each term separately Look for the strongest operations of powers and roots first, then multiply and divide,
Each term simplifies to a single answer and they are then added or subtracted in the last step.
If a weaker operation MUST be done first, it will be shown in parentheses.

To simplify the expression using PEMDAS:
-
Evaluate within parentheses:
( (5 + 22) = 27 )
( (35 - 27) = 8 )
( 6^2 = 36 ) -
Perform exponentiation:
( 6^2 = 36 ) -
Perform multiplication and division, from left to right:
( 27 \times 8 = 216 ) -
Perform addition and subtraction, from left to right:
( 216 + 36 = 252 )
Therefore, ( (5+22) \times (35-27) + 6^2 ) simplifies to ( 252 ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
