I'll give you a question, please answer with step-by-step reasoning process.
John received 20 gifts on his 12th birthday. He received 8 fewer gifts on his 13th birthday. How many total gifts did he receive between those two birthdays?

32
He got 20 - 8 = 12 gifts on his 13th birthday.

So he got 20 + 12 = 32 total gifts.

.

Thus, the answer is 32
