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

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

Step-by-step 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!!!
