【Jokes】English-Math Jokes

[Aeshattaer 10]

I posted some English jokes in the forum for jokes, but they didn't seem to get it, so I'll try again here = ='

One of my brother's high-school classmates wrote this as an answer for a math question:

1) Expand (a+b)^n

A: (a+b)^n

= (a_____+_____b)^n

= (a____________+__________b)^n

= (a____________________+________________b)^n

etc.

:E

What's this? I am sorry that I cannot understand.

I get it.

1) EXPAND (a+b)^n

so he expanded the multinominal.

Here's another english-math joke, it's quite old, you may have heard it before.

Where is 9?

Ans.: seven "ate" nine.

haha.......I'd try to explain to those who didn't get it:p

Actually, "expand" is a mathematical technique which gets rid of the brackets in equations. (I know it's not quite clear...= =' )

For example:

Expand (x+1)^2

= x^2 + 2x + 1

(" ^2 " means square)

However, Aeshattaer's brother's classmate interpreted the word "expand" literally as making things wider... so he simple made the bracket wider....which is naive(H)

What the...*jaw drops*

I just got an email full of these kind of stuff, here's some:

The teacher was teaching the idea of "limit", he gave an example:

　lim 　1　　=∞

x→8　x-8

Then, to see if his students understood, he asked:

　lim 　1　　=？

x→5　x-5

The ingenious students gave a turned-90-degrees five as an answer.

sinx/n

=sinx/n

=six=6

There was a picture, the picture indicated that ΔABC, ∠A=90°, AB=3, AC=4, BC=x

It asked you to "find x"

Someone circled the x with an arrow pointed at it and wrote: "here it is."
