Eloise bought 3 boxes of crackers to share with her friends over the weekend. They ate 12 box of crackers on Saturday and 23 box of crackers on Sunday.

How many boxes of crackers were left over?

To find out how many boxes of crackers were left over, we need to subtract the number of boxes eaten from the total number of boxes Eloise bought.

Eloise bought 3 boxes of crackers.
They ate 12 boxes on Saturday and 23 boxes on Sunday.

To calculate the number of boxes left over:
Total boxes bought - Boxes eaten

Total boxes bought = 3
Boxes eaten = 12 + 23 = 35

Therefore, boxes left over = Total boxes bought - Boxes eaten
= 3 - 35
= -32

Since the result is negative (-32), it means that there are no boxes left over.
