because one of these days, I wont have a Cell Phone, Computer, or even a Calculator, But I will Be presented with a really hard Multiplication problem and Ill just Whip out my Trusty ol` Notebook and Pencil which I always keep with me and BAM! Math Problem = Solved!

Actually... I really like how she essentially turns 87*72 into (8x+7)(7x+2) where x=10... or more drawn out, 8764*3849 into (8x^3+7x^2+6x+4)(3x^3+8x^2+4x+9) where x=10. Longer, but a lot easier... at least to me.

I like that she so seamlessly went from elementary school math to algebra by showing their relation in terms of practicality, which is what all good teachers should do. Unfortunately I couldn`t get over the start of the video where she showed us "tricks" you can use to "simplify" multiplication, as in, turning a 20 second problem in to 2 minutes worth of drawing all over the paper and tediously counting up all the numbers, resulting in even more math problems like adding multiple large numbers. Ugh, just do it the way we were taught it`s the easiest.

I could do the old fashioned multiplication a lot faster than I could draw grids and count dots or multiply every combo and keep track of zeroes! I`d bet most people watching would say the same.

"I could do the old fashioned multiplication a lot faster than I could draw grids and count dots or multiply every combo and keep track of zeroes! I`d bet most people watching would say the same."

Pretty much, I did the first problem in my head in about 3 seconds and the second in about 15.

I feel for this girl. I was like this in 3rd grade; I re-invented speed math in my head and skipped straight to the answer. I was right most of the time, but not always. The teacher thought I was lazy and guessing, didn`t understand the working and sent me to the principle`s office. EVERY DAY.

In the end though, my way of thinking lent itself better to solving commercial problems through computing, and she`s probably dead by now, so I have the last laugh.

When she did 97 x 86, isn`t that EXACTLY the same as the traditional way to multiply that we were all taught in school? Digit by digit, placing the result in the tens (or hundreds) column and adding them together. How ELSE can you multiply?

Either do it that way and waste an entire sheet of paper per question or do it the old fashioned way if you need to show the work. If no work is required, just get a calculator from a dollar store.

- What your math teachers didn`t want you to know.
I`m still trying to figure out her snake video

huh?

Video is a waste of time.

Chinese number gestures.

7x6=(7x7-7)=42

she talks too fast. i have to go back re-hear and enterpit the visuals to grasp it all

(see what I did there?)

that`s her point, you noob

so are we just not supposed to have an example problem? learn 2 common sense plz
