For myself, I love math. I also never understood, even now, the need to spend so much time memorizing multiplication tables.<p>In fact, I&#x27;ve never learnt it. From time to time I still find myself multiplying on fingers; as a kid I used it a lot, now the table went into my head automatically simply from continued usage. The way to multiply two natural numbers from &lt;6; 9&gt; on fingers was one of the most important things my mom tought me :)<p>There&#x27;s also a way as presented in the article (8<i>7 = 8</i>8-8), but I mostly use it when double checking, as I find it slightly more error-prone when doing it in head (and obviously very inefficient when done on paper). Works great for bigger numbers though.<p>Once in junior high school my math teacher caught me on multiplying on fingers and ordered me to learn the table for the next lession. Managed to pass it, but quickly forgot in following days. I never cared - I was always doing very fast and well on math classes anyway.
