Question

How many counting numbers are less than 3 units from the number 4

Answer 1

4

Explanation:

So basically, which numbers are on either side of 4, but not more than 3 units away?

2 3 4 5 6 are all less than 2 units away, and if we don't count 4 the answer is four numbers- 2,3,5 and 6

Answer 2

I'm guessing that by "counting numbers" you're refering to "integers."

Why not actually write out the numbers that qualify, and then count them?

{2, 3, 5, 6} is a set of four numbers, all of which are fewer than 3 units away from the (central) number 4. Some people would include 4 itself in this set.
