"Don't let notation get in the way of your understanding" - beautiful!

Upvoted even though the title got it wrong. Visual multiplication is just normal multiplication done visually. I liked it best when she showed what multiplication really is at the end with the single area of intersecting rows and columns. A friend of mine didn't know that a number squared was called "squared" because it represents the area of a square with sides of that length. How easily we lose sight of the forest for the trees.

I'm gonna save this and show to a client of mine who has huge problems with multiplication. Guess I will have to translate it first though, since her English is pretty bad as well...

Wow, visual multiplication requires a lot more paper than traditional means.

I was amazed when she extrapolated the "standard" multiplication into the multiplication of polynomials. I had never thought of that before...color me dumbfounded (it's kind of like periwinkle)

I just use my calculator.

What does your calculator say about 48÷2(9+3) ?

Ummm... so the video ended before I thought it would.

She could've used that last bit of advice for the tau = 2pi nonsense.

So what the fuck is 7 dolphin'd by 12? Is it going to be in her next video? This New Math shit is hard.

Not necessarily. The statement is ambiguous, which is to say, malformed. This is why, as she pointed out, nobody uses the "÷" symbol.

48
-- (9+3) = 288
2

but

48
------ = 2
2(9+3)

OoO. (edit: plus sign isn't showing up)

48÷2(9+3) or

48/2 = 24
9+3=12
24x12=288
