If the expression #3-4^2+6/2# is evaluated, what would be done last?

Answer 1

The addition

Order of evaluation:

Parentheses (none in this case) Exponentiation: #4^2# Division and Multiplication: #6/2# (no multiplication) Addition and Subtraction: there is a minus and a plus #color(white)("XXX")#-when there are multiple operations at the same level #color(white)("XXX")#they are performed from Left to Right. #color(white)("XXX")#Since the minus appears to the left of the plus #color(white)("XXX")#the minus occurs first (and the plus last).

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.
