Answer 8

you have to make both number to be in 10th like ex: 98+100 = 200 (98 +2) + (102-2) =100+100=200 so the numbers from both sides have to be the same like +2 or 02 it doesnt metter cause the answer is going to be the same .. but when you add that number and make it like a whole with a 0 in the end it's easier to add... do you understand?
