Hello!
We want to find out how many MORE paper clips than pencils Mr. Kim has.
Now, there's a super handy operation called subtraction that we can use to solve this.
To find out how many more paper clips than pencils Mr. Kim has, we must SUBTRACT the amount of pencils from the amount of paperclips:
77 - 14 = 63
So, Mr. Kim has 63 more paperclips than pencils.
