I have twenty cards with the numbers from 1 to 20 on. I want to put them in six piles.

It doesn't matter how many cards are in each pile.

But I want the

**sum**

**of the numbers in each pile to be the same (so when you add the numbers in a pile together you get the same for each pile).**

**Which cards go in which pile?**

I just want to tell you something that if we are only using the numbers up to 1-20 are we supposed to use the numbers once.

ReplyDeleteYes that's right. You have 20 cards, each with a different number on. Each card can only go into one pile.
