1. Traditionally, multiplication tables, are written as:
8×1=8 The next answer is found by adding 8+8 or by knowing 8×2=16, and the next answer is found by adding 16+8 or by knowing 8×3=24, etcetera. That method requires the person to already know the answer he or she is supposed to be trying to learn, or to practice addition (instead of practicing the multiplication they are trying to learn). A claim I am making: with my invention one can write multiplication tables without already knowing the answers. |
