    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.

    You know at least one person is going to be convinced this is easier and is going to have notebooks filled with grids and dots.

    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.

    If she didn`t talk at 2,000 words per second without breathing, it might be helpful. But this is pretty sucky.

    That made me feel like some kind of genius. I can figure out all of those problems in my head way faster than drawing lines and dots then counting.

    "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.

    Video is a waste of time.

    It doesn`t matter whether the `trick` is easier or not. The point was to look at multiplication in a different way. This video was a win.

    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.
