The pair of parenthesis that can be removed without changing the value of the expression is "parenthesis around 5 × 8"
Given expression:
(1 + 2) × (6 - 3) + (5 × 8) + (9 - 4)
Using BODMAS
- B = bracket
- O = of
- D = division
- M = Multiplication
- A = Addition
- S = Subtraction
(1 + 2) × (6 - 3) + (5 × 8) + (9 - 4)
= 3 × (3) + 40 + 5
= 9 + 40 + 5
= 54
Remove parenthesis around 5 × 8
(1 + 2) × (6 - 3) + 5 × 8 + (9 - 4)
By removing the parenthesis around 5 × 8, you still have to multiply before adding according to the rule of BODMAS
Therefore, the pair of parenthesis that can be removed without changing the value of the expression is "parenthesis around 5 × 8"
