Well if you have a calculator then just like for negative and positive buttons and it'll be easy because the calculator will be doing the math, but if all you have is your brain then draw a number line including negative numbers and subtract whatever the positive number is. Ex: (-2) - 5= -7 its mostly the opposite of addition.
EX: (-6) - 4 = -10. To make sure you have the right answer just do the inverse operation. Add.
-10 + 4 = -6. Good Luck!
