"The sum of the square roots of any two sides of an isosceles triangle is equal to the square root of the remaining side."
This of course is incorrect.
Quote: MrVIn The Wizard of Oz when the Scarecrow gets his diploma (instead of a brain) he says the following:
"The sum of the square roots of any two sides of an isosceles triangle is equal to the square root of the remaining side."

You are willing to believe in scarecrows given brains but not flooky math
At any rate he really wasnt given a new brain. It was a fake honorary brain. He was smart to begin with
Just not good at math
However, both are wrong. The actual answer is based on the Pythagorean Theorem, which, in turn, is a corollary of the Law of Cosines, which is:
The square of the length of the side of any triangle equals the squares of the lengths of the other two sides minus two times the product of the lengths of those two sides times the cosine of the angle where they meet. (If it is a right triangle, the cosine is zero, the original side becomes the hypotenuse of a right triangle, and it becomes the Pythagorean Theorem.)
Someone a while ago asked me whether Sines (and by implication Cosines, Tangents etc.) were actually useful in normal everyday life - I'm sure they're used in architecture and cartography but that doesn't count.Quote: billryanMath. Bah. Who needs it?
I wish I'd taken the harder classes as calculus factors I to many business decisions and it sucked having to relive on other people's calculations.
I'm pretty good at guesstimating but sometimes you need an exact figure. Fortunately, I have a strong network of mathletic friends.

It was probably in the script and the director said thats too long. Just cut it down

What else is there to know?

Everyone needs a good understanding of basic math, but according to this report from the
BBC, fewer and fewer of us know enough to figure how to split the check for a shared dinner.
Apparently, increasing numbers of consumers cannot figure out whether the small size at 3 for $1.00 is a better deal than the larger size at 2 for $1.00.
Nor can they adjust a recipe designed to serve four when they plan to serve six at dinner.
They just say they don't need that stuff, and drive away with the "Ignorant and Proud of It!" bumper sticker on their car.
So sad.

Depends on how small the "small" is and how large the "large" is....
I do math every time I go to the grocery store to figure out the best per-ounce price.

My mom always tells me about the $5 supermarket toilet paper Friday sale. I just get my toilet paper at Costco. I finally did a comparison based on square feet. Costco: $0.015/square foot. Supermarket: $0.025/square foot.
