Gemma had 2,034 in her checking account. She wrote a check for 625 to pay the rent on her apartment. After the landlord cashed the check, how much money did Gemma have left in her checking account?

To find out how much money Gemma has left in her checking account, you need to subtract the amount of the check she wrote from her initial balance.

Initial balance: $2,034
Amount of check: $625

Total amount left in Gemma's checking account: $2,034 - $625 = $<<2034-625=1409>>1409. Answer: \boxed{1409}.
