Answer: The required answers are :

(a) 21, (b) 26, (c) 18 and (d) 37.

Step-by-step explanation: We are given to solve the following problems with parentheses solved first.

(a). The given problem is

$4+(5+12).$

We have

$4+(5+12)=4+17=21.$

(b) The given problem is

$(3+6)+17.$

We have

$(3+6)+17=9+17=26.$

(c) The given problem is

$4+(5+12).$

We have

$(3+4)+(5+6)=7+11=18.$

(d) The given problem is

$9+(11+7)+10.$

We have

$9+(11+7)+10=9+18+10=9+28=37.$

Thus, the required answers are :

(a) 21, (b) 26, (c) 18 and (d) 37.
