What does it mean when there is a line under the greater and less 
than symbol?

Hi Elizabeth, and thanks for sending your question to Ask Dr. Math.

The lines means "or equal to," so that 

  1 + 3  <  5      is a true statement because 4 is less than or
         -         equal to 5  (in fact 4 is less than 5)

  2 + 3  <  5      is also a true statement because 5 is less than or
         -         equal to 5  (in fact 5 is equal to 5)

I hope that explains it.  If you need more help with this, please 
write back.
