Complete: What is one less than four?

In this question, we’re shown a group of jelly beans. We don’t need to count the jelly beans because we’re already told that there are four. We have to find one less than four. There’s a big hint in the picture. The arrow is showing us to take one jelly bean away. Finding one less is the same as taking away one. So let’s take away one jelly bean. How many are left? There’s one, two, three. Four take away one is three. One less than four is three. Three is one less than four.
