+-1--1 how can i do this one please ?
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
