Dozenal Multiplication Practice

No thinking in decimal!

Type the answer in the box, then press enter. If your answer is correct, a message will appear and the next problem will be displayed. If your answer is wrong, delete it and try again.

The digits ten and eleven, which I reccomend calling "dek" and "el", are represented by ⱹ and ⸡, respectively. (No, there is no particular reason for this.) They can be typed by pressing d for dek and e for el.

I reccomend calling numbers the same thing you normally would. For example, 34 in dozenal can still be called "thirty-four". ⱹ0 is called "deky," and ⸡0 is called "elly," so, for example, ⸡ⱹ is "elly-dek." You may want to think of 11 and 12 as "oneteen" and "twoteen," or "unteen" and "biteen," or you may find this unnecessary.

If you wish to practice a certain row, or, equivalently, column, of the multiplication table, select the corresponding number from the menu. If you wish to practice square numbers only, select "square."
