Question

How can the addition of a parenthesis be used to increase the value of the following expression?: 4-3/2^2+3*2+5

Answer 1

Put parenthesis around the `2+5` This way the addition must be done before the multiplication

Explanation:

`4 - 3/2^2 + 3 xx 2 + 5 = 4 - 3 /2^2 + 6 + 5 = 4 -3/2^2 +11`

`4 - 3/2^2 + 3 xx (2+5) = 4 -3/2^2 + 3 xx10 = 4-3/2^ +30`

`30 > 11` so adding the parenthesis around the 2+5 increases the value of the expression.

( Note there are also probably other ways of adding parenthesis to increase the value but this way works. )
