Easy Speed Math they Don't Teach You in School - Part 5 - Squaring
Much fun.
I love math...but I didn’t know this. Much nerd fun.
Years ago I tried to learn the Trachtenberg system of system of speed math. I still couldn’t get it!
I thought heaven had come down to earth when the first hand held calculator went on the market.
I didn't know I was good at math until my friend loaned me his Texas Instruments calculator in grad school.
Everything changed. The world became a simpler place.
I am much better at math once the adding, subtracting, multiplying, and dividing are done away with.
The concepts are clean and clear without the bothersome details.
AWESOME!!! Thanks for sharing. I could have gone to UIL math if I’d have known this, LOL!!
When I was young I liked math and scored 99th percentile on the Florida Senior Placement Test. That was as high as one could score.
I recently bought a nice TI calculator and could not even figure out how to work it.
On the other hand my verbal skills do not seem to have gone down.
I worried at first about whether teaching a different technique my confuse students. But now I don't know.

I became a wiz once I could get rid of the tedium.

Let nothing get in the way of you and your potential.
Not to sound corny, but God made you special...a genius in your own way.
Your challenge is to discover your God-given genius and to exploit for His sake (and the world's and yours)
Nice! Thanks for posting.
Way cool, thanks !
My first year of college was in 1973 — the year they eliminated slide rules in Chemistry. By then a four function TI calculator cost 80 bucks, but I found a used one for half that. The next year four function digital watches were available for five bucks.
loved it. thanks.
I would like a “deep” math lesson that demonstrated to me WHY this little “trick” works. That - even more “nerdy”, yes, would be very interesting as well.
The world of mathematics came alive.
And now with MSExcel...I could live in this math world and never get tired or stop learning.
All that said, I do believe that math is God's handiwork...and His gift to me and others.
Math is too perfect not to have a Creator.
It isn't random. It is designed...and carefully--perfectly--so.
Ping me when you do.
I will do the same if I perchance do.;-)
I’ve seen similar videos which I found interesting, but the traditional methods are actually shortcuts compared to these esoteric methods.
What is truly a waste of time are the “NEW” “ENLIGHTENED” methods such as the old NEW MATH and the crap Common Core shoves down teachers’ throats. The time spent screwing around with this nonsense would be better spent in practice, which builds automaticity. Once you just KNOW the results of fundamental computations, you can discard all the methods. Then higher math is a breeze.
The first calculator I ever saw was in a psychology class around 1971. The professor who had just arrived from England said he was surprised to find the department had one.
He passed it around for all of us to see. I have no idea what the functions were but he said it was very expensive.
I think it was around the size of a hymnal.
In 1974 I bought a basic scientific calculator from Sears for $69. It was reduced. It still works and has beautiful green numbers which are easy on the eye.
Their objective is control...not enlightenment.
Control requires ignorance of the Truth.
I see a portrait of Obama staring up at the stars with a glint in his eye.
All a lie...but nicely packaged.
Thanks. It is a TI-nspire cx. It has an unbelievable number of functions.
The real problem is that it did not come with instructions. You are supposed to look them up on the internet and I hate that.
Would much rather have a book of instructions like they used to come with.
