Misc Math

The reverse side of a United States penny has a math lesson.

It is the integral of 1 over cabin d-cabin, which is a natural log cabin.

The math book went to the psychiatrist and said, "Doc, I have are these problems."

There are 10 kinds of mathematicians. Those who can think binarily and those who can't...

If 13 is a baker's dozen, would 169 be a baker's gross?

i only have one thing to say about maths, thank f**K its overrr!!!!! freeeeeeeeeeedom!

Can you tell us how math becomes over?

When the math problem has been solved.

In 2010 there are still six unsolved math problems from: Millennium Prize Problems.

So I guess math goes on!

Next week I will take my final exams, and the school year will come to an end. This year I found a friend, Rachel, whom I thought I had lost. Through her I found another friend, a boy, Jonathan, with Downs Syndrome, whom she tutored in math.

It wasn't tutoring in the normal sense of the word. She played number games with him; and after we reconnected, I played with him too. Mostly we played Bingo. Not the normal Bingo, but a Bingo game with pictures of the fifty states, like California or Texas, instead of the normal numbers.

The first time we played the game, I kept a numbered list of states as they were called in the game, Alabama through Wyoming. The second time I played, Jonathan wanted to keep the list, so I gave him the pencil and the list to see if he could match the states' numbers, one for Alabama through fifty for Wyoming, with the numbers on the list.

He could match numbers like 13 and 21, but he sometimes marked 14 when the number was 41. After we had play together for several weeks, he could match all the numbers to 50.

Rachel and I decided to change the game from 50 to 100 names, and we made a list of 100 hurricane names. Jonathan liked this even better because he is gregarious, and he knows people (friends, relatives, and fictional characters) with most of the names.

At first Jonathan confused numbers like 95 and 59, but now he can recognized every number to 100.

Because of our experience with Jonathan, the special education teacher asked Rachel and I to help with another special education student named Mary. He asked us to be sure she got on the correct bus for the ride home from school.

The wait for the bus lasted about 15 minutes, and while we waited, Mary liked to read the Yellow Pages, which here in the United States is a phone book with business advertisements and phone numbers. She could recognize numbers up to nine.

We were not able to teach her the meaning of 10, which is confusing enough, but if you read a previous post in this thread, 10 means two. And if Moctazuma, the Aztec king were here, he would refer to 10 as the number twenty.

Edit: And we know that since Abraham Lincoln counted by twenties (four score and seven), he must have been an Aztec.

Mathematicians resemble realtors because they both deal with properties.

I read a history of ancient mathematics. I don't remember the title.

The Sumerians counted with a base-10 number system, and they wrote numbers with a stylus on clay. Later cultures, who spoke a language more like Egyptian or Hebrew, sometimes called Babylonian, used the stylus and clay; but they counted with a base-60 number system, which continued to be used even by parts of the Roman Empire.

Modern societies still use the base-60 system to tell time.

People speculate about why base-60 was so popular. For example, it made some fractions like 1/3 easier to write. Maybe 60 had some religious meaning like base-20 numbers had some special appeal to the Central Americans.

I suspect that one reason might have been the fact that 59 was the largest single digit number, which could be easily written with the stylus.

Mathematicians don't go to the beach because they have a sine and a cosine to get a tan and they don't need the sun!

f*** trig.

Salaam aleikum.

I divided by zero and the paper caught on fire, so I couldn't do my math homework.
