+1
In math class, when writing -1 and then realizing the answer is positive 1 so you draw a line through the minus sign and it looks like you are retarded.
teacher: So as you can see the answer becomes -1...
*students write -1*
teacher: ...but since it's a negative times a negative it becomes a positive 1.
*student make their -1 a +1*
