A useful example

r1c2 < r1c3 means row 1 column 2 is smaller than row 1 column 3. Your next round may have a different position, so inspect it before acting. Read the matching step again.

Pay attention to this rule

An inequality specifies order, not an exact difference. Check the rule before repeating the action. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
