I wonder what year schools stopped teach stuff that seemed so basic when I was learning it. I knew it was going to be important to memorize multiplication tables and I think I knew that memorizing all the Presidents in order wouldn't be all that important. Seems instinctual. YMMV When did they start allowing HS students to use calculators? |

Math has the additional benefit of disciplining the mind.
Abraham Lincoln studied Euclidean Geometry to learn logic in order to develop his skills in presenting arguments as a lawyer. |

I can't say I "memorized the tables" like visualizing it...
But I'm pretty fucking good at doing multiplication in my head. |

Yes, I learned them up to 12x12. It is really handy when estimating material needed, estimating costs, etc in my head. A really useful skill to have, and it saves the time of needing a calculator. Additionally, it makes you look smart these days. It used to not be a big deal, but now folks seem amazed that I can get a rough guess in my head quickly with no calculator or paper. |

Times tables up to 12x12 is probably the one math thing that I use the most.
Doesn’t matter if you do rocket surgery or drive truck, it’s useful. And if you want to do any math at all, algebra, calculus, whatever you are at a significant disadvantage if you have to whip out a calculator for 7x8. |

I didn't memorize them, but I'm pretty good at doing the calculations in my head.
Not really multiplication related, but my wife struggles with math in general. So we're laying in bed the other night and talking about the stupid raised garden beds I'm building her. I ask her if she thinks 18 inches is deep enough. After a few seconds of silence I look over and see that she is using her thumb and forefinger to approximate an inch and then stacking them on top of each other while counting to 18. 
I'm like "18 inches is a foot and a half. You can't picture a foot and a half? How about a cubit? Holy shit woman!" Her excuse is that since she did hair for 20 years, she automatically thinks in inches. Like "Just take about 4 inches off the back".
So she's never living that down. I guess I should have just told her to picture my dick.  ....And then multiply by 6.

When I went on long drives (say 3 days coast to coast) in a car without a radio, I used to pick wo 3-digit random numbers and multiply them in my head, then I would take the result and divide it in my head. It got to the point I could predict the top three digits and the bottom three digits faster than people with calculators could punch in the numbers and hit equals.

Memorizing times tables seems like a total waste of time and mental resources. Once I learned it -- and it was not difficult -- it became rote memory recall. I taught myself the 11X and 12X tables later, because it seemed like handy knowledge. We didn't have calculators back then. And I can give you an answer before you can get the calculator app on your brain-substitute phone launched. |
