Answer 1

Sum of -200 and -221

$- 200 + ( - 221) \\ = - 200 - 221 \\ = - 421$

Difference of -531 and -721

$- 531 - ( - 721) \\ = - 531 + 721 \\ = 190$

$190 - ( - 421) \\ = 190 + 421 \\ = 611$

Answer 2

Answer

Sum of -200 and -221.

= -200+(-221)

= -200-221

= -421.

Difference of -531 and -721.

= -531-(-721)

= -531+721

= 190.

Now subtract the -421 from 190.

= 190-(-421)

= 190+421

= 611
