Answer 1

Answer:

-3-4= -7

Step-by-step explanation:

Dear, (+) (+) = +

(-) (-) = +

(-) (+) = –

(+) (-) = –

• whenever we add any numbers of same signs we always add them and put the same sign.

• whenever we add any numbers with different signs we always subtract them and put the sign of the

greater one.

for eg. +3 - 6 = -3

-6 -14 = -20

Now according to your question,

-3-4= -7

I hope it will help you!!

if any doubt u can ask

Answer 2

(-3)+(-4)

-3-4

$we \: know \: that \: ( - ) + ( - ) \: is \: always \: ( - )$

now if we add them it will sum up to 7 and the sign will be negative since negative + negative is always negative.

so the final answer is -7
