Think of negative numbers as cold numbers and positive numbers as hot numbers (just like with temperature)

if you add cold into a room then the room will get colder   SO  +- = -

if you take cold out of a room then the room will have to get warmer.    SO   - - = +

SO

+-1--1 =  -1 +1 = +1 - 1 = 0
