Question

-10-5= _ can anyone tell how to get to know that we have to put negative sign or not because it's negative no.then also we moved towards left​

Answer 1

Answer:

-15

Step-by-step explanation:

-10-5= -(10+5)= -15

Answer 2

Answer:

So let us assume we have to find x.

and we solved the problem and brought down the answer to x= -10-5(we are adding two negative numbers and mark their sign as -)

so we know x= -15.

if we were asked to find the value of -x,

then, we change the symbols in both sides,

-x=15. or 15= -x.
