5 eggs are left over.

Explanation:

Computers love this question. They have a built in command called mod which will give the answer in one line.

L = (85 + 28) mod 6: Print L

Humans have a little tougher time with it. We do it like this

Add 85 and 28 = 113

Divide by 6

113 / 6 = 18.8333333

What is left over is 0.833333333. But what does that mean, and how do you get rid of it?

Answer Number of Trays: The 18 is easily explained. He can fill 18 trays.

But we still have 0.83333333 to deal with.

The simplest way is to multiply that by 6.

6 * 0.833333333 = 5

The answer is 5
