# How do you evaluate #10+8-:2-4#?

Using PEMDAS you get 10

Parenthesis

Exponents

Multiplication

Division

Addition

Subtraction

There are no Parenthesis, Exponents or Multiplication so we skip those steps and move on. First we divide 8 by 2 and you get 4.

Then you add 10 to 4, you get 14.

And finally, you subtract 4 from 14 to get 10.

PEMDAS is an acronym for the words parenthesis, exponents, multiplication, division, addition, subtraction.

Given two or more operations in a single expression, the order of the letters in PEMDAS tells you what to calculate first, second, third and so on, until the calculation is complete.

To evaluate the expression (10 + 8 ÷ 2 - 4), you follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

(10 + 8 ÷ 2 - 4 = 10 + (8 ÷ 2) - 4)

(10 + (8 ÷ 2) - 4 = 10 + 4 - 4)

(10 + 4 - 4 = 14 - 4)

(14 - 4 = 10)

Therefore, the value of the expression is (10).

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.
