the minus sign outside the -20 represents an unwritten or implied negative one that is multiplied by the -20 so the problem is really 8 added to neg 1 times neg 20 so using order of operations you first multiply -1 times -20 to get 20 then add 20 to 8 to get a total of 28.

two minus signs next to each other will change the sign to positive so 8 - (-20) = 8 + 20 = 28

The minus sign outside the parentheses changes the sign of everything inside the parentheses. So it becomes:
8 + 20 = 28.

8-(-20)=8+20=28
the minus sign and the negative change it to a positive or plus...

Here's how you can remember:
Mary Mary Quite Contrary, How do your integers subtract?
Change the sign of the second number and add as a matter of fact!
(using this, change -20 to +20 and then add them together)

negative plus a negative equals a positive, so 8-(-20) is just 8+20. Good luck.
