**MATH!**

The sum of two prime numbers is the prime number 89,563. Find the smaller of the two addends. I attempted the problem but I'm not sure if it is right. 89,561 is a prime number and so is 2. So is the answer 2?

Okay I understand. I just wasn't sure if rearranging the tiles (putting them in a different order) would be considered another rectangle. But I get it now. With the answer being 1. Thank you.

**Math**

So mixing them up doesn't make it another option? I'm assuming that this problem is a trick question.
*May 6, 2011*

**Math**

But I don't know for example,say you labeled each tile A, B, and C. Is there an option to lay them in different orders, or does that not matter because they are all the same tile? Also is another way, to lay it down as a coloum instead of a row?
