Alpo Posted May 25, 2019 Share Posted May 25, 2019 In the book it's early 1897. The girl is thinking about math, and says, "I knew my multiplication tables to 20 x 20, like everyone else...". 20 x 20? I was taught to 12 x 12. If it's higher than that I can FIGURE IT - for example, 14 x 18. That's the same as 9 x 28, which is 180 + 72, 252. But I don't KNOW IT. Anything up to 12 x 12 I KNOW. I memorized it. Higher than that and I have to think about it. Link to comment Share on other sites More sharing options...
Alpo Posted May 25, 2019 Author Share Posted May 25, 2019 I wonder if they even teach the multiplication tables any more? I learned 'em in the fourth grade. How 'bout y'all? Link to comment Share on other sites More sharing options...
Marshal Mo Hare, SASS #45984 Posted May 25, 2019 Share Posted May 25, 2019 Second grade. It wasn’t taught in the second grade, I picked up someone else’s multiplication tables card and learned it. Downside, third or fourth grade was soooooo boring., but I was out sick for five weeks and eventually happy that everyone else caught up to me.

J-BAR #18287 Posted May 25, 2019 Share Posted May 25, 2019 I knew them up to 25x25 in engineering college, it came in handy on some quiz questions, but haven’t tested myself in years. I’ll get back to you, especially if I do well! Link to comment Share on other sites More sharing options...
Subdeacon Joe Posted May 25, 2019 Share Posted May 25, 2019 We had to memorize through 12 x 12. My wife's kids, born in '83 & '84, didn't have to memorize any of them. Link to comment Share on other sites More sharing options...

Pat Riot Posted May 25, 2019 Share Posted May 25, 2019 I only recall learning up to the 9’s. Multiplication tables bored me and for some reason I just could not memorize them. I was that kid that always got the question “Quick, shat’s 7 times 8?” And then I would get the “look of disdain” from Mrs Lively and then she would move on to the next kid. I really disliked that woman. I wonder if I wouldn’t learn the “Times Tables” just to irk her. I was a weird kid... Link to comment Share on other sites More sharing options...

Rye Miles #13621 Posted May 25, 2019 Share Posted May 25, 2019 I learned up to 12 X 12, I can figure out easy ones above that like 20 X 16 etc. but when it comes to for ex: 17 X 43, I use the old 17 over 43, or the calculator!! 17 X 43 _______ 51 680 _________ = 731 Link to comment Share on other sites More sharing options...

Dustin Checotah Posted May 27, 2019 Share Posted May 27, 2019 I remember a kid when I was in grade school that learned to use a slide rule because he said he could not remember his multiplication tables. I learned later how to use a slide rule in physics class. The example above with 17 X 43 I tried with the top slide rule in picture and with my older eyes I got close with 730 but it was just a tad over the line and that is where it is handy to be able to extrapolate. When I was in the Navy's nuclear power school it would get me close enough for government work. Link to comment Share on other sites More sharing options...
J. Mark Flint #31954 LIFE Posted May 28, 2019 Share Posted May 28, 2019 I've traveled thousands of miles from home without forgetting the multiplication tables. Astronauts went to the moon and didn't forget them, so I am going with 239,000 miles- after that it is unknown. Link to comment Share on other sites More sharing options...

When I was in the Navy's nuclear power school it would get me close enough for government work. My younger daughter tutors a bunch of high school students in math, science and English. I was over to her house one day, and brought one of my slide rules to show the kids. They had never seen one! Showed them roughly how to work it, but they preferred using the calculators on their I-phones or laptops. I asked what they would do if the power failed or their batteries ran out. They just sort of looked at me...like what planet did you come down from? Yes, I learned up to 12 x 12. Pocket calculator is handy for higher and more complicated. Otherwise, I resort to a pencil and paper. Anybody remember how to do long division, or square-roots longhand? Link to comment Share on other sites More sharing options...
