Answer:
Sebastian is correct
Explanation:
George is wromy because where he had to simplify:
+ 5 - 8 ( which is the same as - 8 + 5 ), he added the two numbers (5 and 8) which is not supposed to be so. He should have rather subtracted the 8 from the five which will be + 5 - 8 = 3. This then makes Sebastian correct as he subtracted the two numbers.
