Maths Jokes

Interesting facts about Mathematics

If a class has 23 students in it then the probability that at least two of the students share a birthday is about 0.5. Surprised? If there are 50 students in a class then it's virtually certain that two will share the same birthday. This seems to go against common sense but is absolutely correct.

Math jokes

Teacher: What is 2k + k?
Student: 3000!

Q: Why do you rarely find mathematicians spending time at the beach?
A: Because they have sine and cosine to get a tan and don't need the sun!

Q: What does the zero say to the the eight?
A: Nice belt!

Q: What does a mathematician present to his fiancée when he wants to propose?
A: A polynomial ring!

Q: What does the little mermaid wear?
A: An algae-bra.

Number Pyramid

Hello! Heres another interesting video on maths. It is supposed to be amazing. Try to think of why this the numbers are in this pattern. Please enjoy the video.

Thought of why the numbers are in this pattern. We will try to come up with answers as soon as possible. So stay tuned to our blog!!!

Strange properties of the number 666

I have found this strange and creepy piece of article from the Internet, I am sure it will give you the goose bumps to see how freaky it is.

The last book of the Bible, Revelation, brings up the number 666 as being the number of the beast connected with the end of this age and the coming of the Messiah. You will find the direct reference in Chapter 13, verse 18 of Revelation. Besides that cataclysmic reference, the number 666 has quite a few very interesting properties.

666 = 3^6 - 2^6 + 1^6

666 = 6^3 + 6^3 + 6^3 + 6 + 6 + 6

(Mike Keith mentions that there are only five other positive integers that exhibit this property...find 'em!)

666 = 2^2 + 3^2 + 5^2 + 7^2 + 11^2 + 13^2 + 17^2

666 = 1 + 2 + 3 + 4 + 567 + 89 = 123 + 456 + 78 + 9 = 9 + 87 + 6 + 543 + 21

Moreover, 666 is equal to the sum of the cubes of the digits in its square (666^2 = 443556, and the sum of the cubes of these digits is 4^3 + 4^3 + 3^3 + 5^3 + 5^3 + 6^3 = 621) plus the sum of the digits in its cube (666^3 = 295408296, and 2+9+5+4+0+8+2+9+6 = 45, and 621+45 = 666).

Incredibly, the number 666 is equal to the sum of the digits of its 47th power, and is also equal to the sum of the digits of its 51st power. That is,

666^47 = 5049969684420796753173148798405564772941516295265

666^51 = 9935407575913859403342635113412959807238586374694

and the sum of the digits on the right hand side is, in both cases, 666. In fact, 666 is the only integer greater than one with this property. (Also, note that from the two powers, 47 and 51, we get (4+7)(5+1) = 66.)

Mr. Keith also points out that if we assign numerical values for the letters of the alphabet starting with A = 36, B = 37, and so on, we find that the letters in the word


From contributor James Watt comes the following: "Here are some other neat things about 666 I seem to have
discovered (since I never found any reference anywhere else). 6+6+6 =18 and 18 x 37 = 666.
Similarly, 4+4+4 = 12. 12 x 37 = 444. etc. In Roman numerals (and the Greek equivalents), which John would have used
to write them, it is DCLXVI, the exact sequential descending order of Roman Numerals.
Now 1/81 = .012345679012345679012345679.... Notice the 8 is missing. 1+2+3+4+5+6+7+9 = 37.
The other 'number of the beast' is called the vulgate number. It is 616. If 'vulgar' Roman numerals are used in
ascending order, vulgate Roman numerals 616 is IVXCD. The'L' is missing."


I assume that some of you have seen this video before. It is on the chances that we have when making guesses. This video is from a serial movie: N3mbers. Please enjoy the video :D

Interesting right? Hope you enjoyed and gained something from this video.
