Even better in my opinion.
where are shows …
where are shows like this today? and we wonder why kids are retarded watching tv trash
I used a slightly …
I used a slightly different method to prove it. Basically, a three digit number can be written as ax^2 + bx + c, where x = 10. Then reverse the coefficients and subtract, assuming that c < a. You should, after doing two-column borrowing get the result = (a – 1 – c)x^2 + 9x + (c + 10 – a). Adding the first and last resultant coefficients together, all variables cancel out.
Here’s a challenge. …
Here’s a challenge. Let x = 10 and then use quadratic polynomials to prove this trick for any coefficients a, b, c. (Hint: the truism 1x^2 = 9x + 10 is helpful when you try to “borrow”.)
UNLESS the ones …
UNLESS the ones digit is 0……. then the answer is 0.
When it comes to …
When it comes to cartoons that teach different kinds of math skills, Dirk Niblick is one of the best!
Who in the …
Who in the came up with this trick?? OMG those ancient mathematicians and their tricks!!! I guess all they had to do back then was think of mathematical equations! LOL
this is like school …
this is like school house rock
Wow. Another …
Wow. Another Interesting Dirk Cartoon. I Wonder If Anyone Has An Episode Of His Mom Talking To Dirk About Her Favorite TV Show Mathnet. So If Anyone Has Any Clips Of That Episode Put It On Here.
Also, Dirk and …
Also, Dirk and Roger share the same voice actor: radio legend Gary Owens.
I think when you …
I think when you reversed it…you reversed 4 and 3 to 143. When you reverse it you should get 431. So, 431-134 = 297 = 99(4-1) = 99 * 3.
The reason you use 4 & 1 is because they are the first and last digits of the larger number 431.
i’m not sure i get …
i’m not sure i get this, i chose 134 and nowhere in the middle do i have a 9? could you explain it to me!
An amazing little …
An amazing little fact is that you can see the influence of Roger Ramjet in the series, mainly due to the writer of the previous, Jim Thurman, would later go onto work for Children’s Television Workshop.
Yea ! and 9/99 = 99 …
Yea ! and 9/99 = 99/999 = 999/9999 This is the good stuff of pure mathematics !

“don’t fall into the river while you’re playing bridge!, i guess she had to go” hahaha
does any1 have the …
does any1 have the math brigade episode where fluff and fold noodleman were sold a record store for $1,000?
“shoot” LOLOL!
“shoot” LOLOL!
Agreed!
Agreed!
that’s right, i …
that’s right, i just did that in my head
I got zero.
=D
I got zero.
=D
And the reason this …
And the reason this works is because of the multiples of 99.
Assume 100x + 10y + z the larger three digit number
100z + 10y + x
100x + 10y + z – (100z + 10y + x) = 99(x – z).
Q.E.D.

Exactly why they …
Exactly why they need to put this show back on PBS.
That trick is EASY!
That trick is EASY!
Wow. Because of …
Wow. Because of this video I realized I had forgotten how to do multi-digit subtraction by hand. Thankfully I quickly retaught myself.
