FastMultiplicationTable

The purpose of the app is to help elementary students to build a solid math fundation by teaching them the most effective way to remember multiplication formulas.

The app arranges the multiplication table as triangle form so students just need to remember a number times a larger (or equal) number, making them conciously apply Commutative Property of Multiplication, while cutting the memorization in half.

In additional to minimum amount of memorization, the app also teaches students to recite only the words of multiplier, multiplicand, and product, cutting the words "times" and "equal" out. This is the fastest way to retrieve the multiplication formulus.

The triangle shape table has multiplier on top edge (dark green), the multiplicand on left edge (light brown) and product inside.
The app display the reciting words in first text field and the math formula in second text field when product is touched. It also auto plays the reciting sequence when any number on the edge is touched. The "X" button is used to clear the display.
