Answer:

see explanation

Step-by-step explanation:

10 - 8 - 2 ← perform the first subtraction

= 2 - 2

= 0

while

10 - (8 - 2) ← evaluate parenthesis

= 10 - 6

= 4

Because you do the subtraction in the parentheses first. Like 10-(8-2)=10-6=4 but 10-8-2=10-10=0

But when it is 10+(8-2) you just add everything together
