4 IF AND Statements in one cell

Question

Trying to get two equations to then present one of four options.

Example:

Have no idea where to start, all four need to sit in the one cell.

Answer 1

=IF(AND(O34 > O33; Q34 > Q33); Z28; 
 IF(AND(O34 < O33; Q34 > Q33); Z29;
 IF(AND(O34 > O33; Q34 < Q33); Z30;
 IF(AND(O34 < O33; Q34 > Q33); Z31; ))))

If you want to include equality add = behind >< like: <= or >=.
For inequality use: <>. Also, AND can be changed to OR if you need such logic.
