use:- formula:

• (+)×(+)= +
• (-)×(-)= +
• (+)×(-)= -
• (-)×(+)= -

$\underline\mathfrak\green{question}$

a) (-17)+(17)

= 0

is the answer because (+)×(-)= - so, -17+17 = 0

b) (-89) + (+130)

= 41

when you will subtract 130 from 89 you will get 41 by putting greater number sign.

c). (120) + (-85) - (-90)

= 125

subtract 120 from 85 then you will get 35 then add 90 to 35 you will get 125. by putting greater number sign.
