#8#

Count the number of terms first. There are two terms:

Simplify each to a single answer which can be added or subtracted in the last step.

Do the division fisrt

#color(blue)(12" ")color(red)(-" "8div2)# #color(white)(aaaaaaaaaaa)darr# #=color(blue)(12" ")color(red)(-" "4)#

To evaluate (12 - \frac{8}{2}), follow the order of operations, which is PEMDAS (Parentheses, Exponents, Multiplication and Division - from left to right, Addition and Subtraction - from left to right).

First, perform the division:

[ \frac{8}{2} = 4 ]

Then, subtract 4 from 12:

[ 12 - 4 = 8 ]

So, (12 - \frac{8}{2} = 8).

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.
