Hello, In the Message Window:
x = -1 y = 1 put x,y -- -1 1 put -x -- 1 -- if I'm right, when two minuses collide, do they produce a plus? put -y -- -1 put -(-x) -- -1 -- if I get it right, the result is -1 because initially x is -1. So, in brackets we assign it to minus again, and it becomes a plus, but outside the brackets it is assigned to minus again. So my question is: how come? How come two minuses produce a plus? Or do I have to go to infants' school again? put -(-y) -- 1 -- same here. The initial value of y is +1. In the brackets it is assigned to minus, but outside the brackets two minuses collide and produce a plus again.
