Question

Please explain to me how the adding of two negative numbers equals a positive number. When they were shoving number lines and set subset theory at me, this issue came up and I never got a good answer.

Answer 1

eg. -2-2=-4
when two negative sign comes we want to add and put the negative sign because when the sign are same we wanted to put that sign itself
eg. +2+2=+2
