atari2600land has updated “Kindercomp” once more.

Release notes:

Addition is now added. It’s listed in the menu under “ADD.” Basically, it’s like Fun With Numbers where you scroll through the available answer numbers using the joystick and putting in your answer with the fire button. If you respond correctly, it goes to a new math problem. If you answer incorrectly, it still has the same problem for you to answer until you get it right. The code still refers to this game as “Math” because I didn’t know whether to call it Math or Add. Oh, and I bumped the size up from 8k to 16k. I think I’ll call it quits for today.
