Answer 2

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.
