Question

6 + 12 x 8 - 3; value: 141 • Evaluate the expression without the parentheses. Try placing the parentheses in the expression so the value is 141. Think: Will the placement of the parentheses increase or decrease the value of the expression?

Answer 1

Answer

The placement of the parenthesis increases the value of the expression.

Explanation

Without parenthesis, the expression will be evaluated according to the rules of PEMDAS or BODMAS which explains that multiplication takes precedence over the addition and subtraction signs.

6 + 12 × 8 - 3

= 6 + 96 - 3

= 99

But if we introduce the parenthesis, we can manipulate this to give the required 141

If the 6 + 12 is placed in the brackets, then, we can solve this to obtain 141

(6 + 12) × 8 - 3

= (18 × 8) - 3

= 144 - 3

= 141

Hope this Helps!!!
