For Problems 15-26, simplify each of the numerical expressions.

4 ( 3 ) 12 ÷ ( 4 ) + ( 2 ) ( 1 ) 8

To determine

To simplify:

The given numerical expression.

Explanation

Given:

The numerical expression 4(3)12÷(4)+(2)(1)8.

Approach:

The rules for the order of operation in an expression are

(i) Perform all operation within parenthesis ( ), brackets [ ], or other grouping symbols such as fraction bars, starting with the innermost set.

(ii) Evaluate any expressions with exponents.

(iii) Multiply or divide in order from left to right.

(iv) Add or subtract in order from left to right.

Calculation:

In the given expression 4(3)12÷(4)+(2)(1)8, first of all evaluating all parenthesis, we get

4(3)12÷(4)+(2)(1)8=1212÷(4)+28

Changing subtraction to adding the opposite, we get

1212÷(4</
