Learning to Multiply by 12 – CardDroid Math Flash Cards Tip

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!

One of you recently asked how to create a problem set for practicing multiplication by 12 in CardDroid Math.  It’s easy – here’s how:

1. Tap “Settings” from the main screen.
2. Tap the “Customize Problem Set” button.
3. Tap the “x” button at the top of the screen for multiplication.
4. Drag the boxes on top slider so both boxes are on the 12. (If it looks like there’s only one, just slide it to 12, and then slide the one underneath to 12 too.)
5. Drag the boxes on the bottom slider to the number range you want (for example, 2 through 12).
6. Tap back and it’s set!

You’ll see example problems on the screen. You can adjust it until it’s exactly what you want.

Have fun and happy learning!
