Answer 1

Q.1) 1st integer=x

2nd integer=-431

SUM= -231

-431+x=-231

x=-231+431

=200

1st integer=200

2nd integer=-431

THEREFORE,OTHER INTEGER=200.

Q.2)

{-511-(-711)} - {-143+(-557)}

(-511+711) - (-143-557)

200-(-700)

200+700

900

THEREFORE , THE ANSWER IS 900

Q.3)

Let number to be added=x

ACCORDING TO THE QUESTION

-936+x= -543

x= -543+936

x=393

THEREFORE,393 SHOULD BE ADDED TO -936 TO OBTAIN -543.

Q.4)

Let number to be subracted =x

ACCORDING TO THE QUESTION

-250-x= -1000

-x= -1000+250

-x= -750

x=-750/1

x= -750

THEREFORE, -750 SHOULD BE SUBRACTED FROM -250 TO OBTAIN -1000.

Q.5)

SUM OF -235 & -365 = -600

ACCORDING TO QUESTION

(Sum of -235 & -365)+x = 200

-600+x=200

x=200+600

x=800

THEREFORE,800 SHOULD BE ADDED TO THE SUM OF -235 & -365 TO OBTAIN 200.
