Hi, I have numbers that I would like to compare to each other and determine their relationship to each other as to "" or "<". Example

A B
1 50 70
2 10 2
3 (result will go here

Is there any formula that I can enter into cell A3 to identify all the numbers to each other and return the following result?
A1<B1, A2<B2, A1A2, A1B2, B1A2, B1B

I would like it in this form and not in "true or false" form. I use Excel 97
Thank you to anyone that can help
