because when we subtract 5 from we got only one and if we subtract -5from 0 u not subtract any no

Answer 2

Step-by-step explanation:

if both no. are having + sign than we add the no.

if both are having -sign we still add the no.but sign will be -

some proprites of addition:

1. + + =+

2. - - =add the no. but negative sign is used I. e -

ex: -5-5=-10

3. - + or + - =in this case we subtract both the no. but we use the sign of greater no. example..6-5=1 subt. and sign of greater no.that is + because 6 is greater than 5

example 2. 0-5= -5 (0 is having + sign so + - =+ and sign of greater no.i.e.-5 is answer
