What is the simplified form of each expression?

5(14 - 2)^2 ÷ 2

We at present undergo the following operations: addition, subtraction, multiplication, and division. When given an expression sometimes we confuse operations which must take precedence.

In the 1500s the rules of the order of operation were issued. The "order" of these operations states which processes take precedence (as a priority) before which other operations.

The priority of operations is:

Let's implement the rule.

Subtract 14 by 2 in parentheses.

Squaring 12.

... (Equation -1)

Multiply 5 by 144.

Divide 720 by 2 and we obtain a simplified result.

Or from Equation-1 we divide 144 by 2 first.

The final results keep the same.

Another example

Add 2 by 1 in parentheses.

Squaring 3.

... (Equation-1)

Divide 24 by 4.

We get a simplified result, i.e.

Beware of this. From Equation-1 we are disallowed from multiplying 4 by 9. Remember the priority operation rules that have been stated above.
