Its subtraction
it means decreasing a number from another no.
the sign is (-)..we call it MINUS
FOR EXAMPLE
10 - 5 = 5
24 - 6 = 18
so we decrease the no. which is after the minus sign with the number before the sign.
Subtraction Of Integers
20-40= -20
why?
because if we subtract 20 from 40 we get 20 so we are right now subtracting 40 from 20 so the answer would be with a minus or negative sign
hope it helps
