Nothing more to say. Help needed!
Yes, yes you can. But instead of +, you use -. Negative negative = positive.
local negativeNumber = -5 print(negativeNumber) -- console: -5 print(-negativeNumber) -- console: 5
A better way to answer this is math.abs. The function always returns a positive number, regardless of wether the input is positive or negative. If you know basic math, this is just an absolute value function.
