Answer 1

grab your answer....

I am giving the answers of marked questions in order-

-23-(-1050+810)

-23+1050+810

= 1837

2. [136+(-272)] - [-250+138]

[ 136-272] + 250-138

-136+112

-24

3. [33+(-47)] - (-84)

[33-47]+84

-14+84

70

4. let the unknown number be x

x+170= -13

x= -13-170

x= -183

5. it's just like the fourth one so , again let the unknown number be x.

x+( -47)=65

x=65+47

x=112

perhaps it will be enough to clear your doubts, thanks.
