Which of the of the following will negative sign?
​

Answer 1

The number with a higher numerical value will have its sign taken in the answer when dealing with integers.

In the multiplication of signs:

+ × + = +

- × - = +

+ × - = -

- × + = -

(A)  -48 + 79 = + 31 ( 79 is greater than 48)

(B)  -40 + 40 = 0 (Both have equal values with opposite sign)

(C)  -18 + 30 = 12 ( 31 is greater than 18)

(D) 48 + (-39) = 9 ( 48 is greater than 39 )

Hence, none of the options given will answer with a negative sign.
