Lizzy: James has 20 friends. Yesterday at work he got into an argument with 2 of his friends. Now he no longer considers them as friends. On his way back home, he made one more friend. So how many friends does James have left?.
Me: Hmmm, let me think. I think this is the detailed solution:
James lost 2 friends, so he has 20 - 2 = 18 friends left. Then he made 1 friend, James now has 18 + 1 = 19 friends. Final answer: 19.
