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.
