Order of operations

If you made it through middle school, you (hopefully) know of the mathematical order of operations, known as "PEMDAS". This simple string of letters tells us the order in which we do math when we come across an expression with more than one operation in it. ICE properly follows this order. For those who don't remember, the order is:

Operation	Explanation
Parenthesis	Do what is inside parentheses first.
Exponents	Solve the exponents (this includes roots).
Multiplication and Division	Both at the same time, from left to right.
Addition and Substraction	Both at the same time, from left to right.

This means that if ICE comes across 8+(40−7∗2), it will do 7∗2=14, then 40−14=26, then 8+26=34.
