Answer 1

Answer:

check the answers.

Step-by-step explanation:

when we multiply two numbers as well as signs

for example: (-3)×(-5) = (-) (-) 3×5 = +15

some methods of multiplication of signs:

(+) (-)= -

(-)(+) = -

(+)(+) = +

(-)(-)= +

when we add or subtract numbers for example:

-3-5 = here (-)(-)=+ i.e., we have to do plus

5+3=8 and we put the sign of larger number.

so sign will be (-)

therefore-3-5= -8
