As of version 2.7 of CardDroid Math Flash Cards this is easy since there’s a built-in problem set for 12 x [1 to 12], which means to include multiplication problems for 12 times any number between 1 and 12. Just go to the settings screen (tap the “gear” icon on the home screen), tap “Load a Built-in Problem Set,” choose the multiplication icon toward the top of the screen, now scroll down until you see “Multiplication: 12 x [1 to 12] = ?” or “Multiplication: [1 to 12] x 12] = ?” If you want to customize the problem set (for example, to focus on 12 times larger numbers only), follow the instructions below. Happy multiplying by 12!
