Answer:
< is for AND
> is for OR
*important* - this only applies if x is on the left (like x < 7) ( not like 7 < x )
Explanation:
one thing that helped me a lot when I was learning this is to remember this symbol < is like an alligators mouth it's "eating" or opening up to the bigger number if that makes sense so if x > 7 then it's x is greater than 7. if if that doesn't make sense you can always think of it as the arrow is pointing to the smaller number.
as far as AND and OR something my teacher taught me is this: if it's this x < 7 then it's less thAND
and if the arrow is this way x > 7 it's greatOR
AGAIN this is all assuming x is on the left side of the arrow bc that's the way most teaching do it
hope this helps
