Mathematics is a magic, Mathematics can be fun! You might not realize but there are significant mathematical ideas behind many thought-provoking games with numbers, logic puzzles, magic squares or other mathematical tricks.
Have you ever heard of Four 4's Puzzle ?? The idea of this puzzle is that one can write mathematical expressions with results equal to the values from 0 to 100, by using four 4's and any combination of mathematical operations. For example,
- 0 = ( 4 + 4 ) -- ( 4 + 4 )
- 1 = ( 4 + 4 ) / ( 4 + 4 )
- 2 = ( 4 * 4 ) / ( 4 + 4 ) and more on...
You can try yourself for the rest portion of the solution. Don't wanna try ?? hmmm...no problem, just go to this page, where the entire solution of this puzzle is listed.

Do you know about the five most important & fundamental numbers in mathematics ?? They are :
- Euler Number ( e ≈ 2.718... )
- PI ( π ≈ 3.14... )
- i representing the imaginary number √(-1)
- 0 and
- 1
Among those numbers, PI (π ≈ 3.14) is really an amazing one, But what's special about it ? The exact value of PI (π) has an infinite decimal expansion: its decimal expansion never ends and does not repeat. This infinite sequence of digits has fascinated mathematicians and over the last few centuries, lots of research works have been done for computing more digits and investigating the number's properties. So far super computers have been able to figure out up to 6.4 billion digits of π after the decimal point. Wanna know the first 100,000 digits of PI (π) ? just go here . Believe it or not, you can even search for your birthday in PI (π) ! Just try here and find out whether you are in PI (π) or not. Know more about PI (π) from Wikipedia. Btw, do you know that March 14 is an unofficial celebration for PI(π) Day derived from the common three-digit approximation for the number π ≈ 3.14. Know more about this PI(π) Day from here.
The Euler Number (e) is also an important mathematical constant commonly used in the exponential models. Like PI (π), it has also got infinite sequence of digits after the decimal point. You can know the exact value of Euler Number up to 10.000 digits from here.
There exists a mathematical equation combining all the five fundamental numbers (mentioned earlier) known as Euler's Formula . This equation also includes addition, multiplication, exponentiation and composition - four of the fundamental operations of mathematics : eiπ + 1 = 0.

Now, let's talk about Prime Numbers . We all know, a number is said to be prime when it has exactly two distinct natural number divisors, which are 1 and the prime number itself. But, how many primes do exist ? and what's largest prime number ? On December 15, 2005, Dr. Curtis Cooper and Dr. Steven Boone, professors at Central Missouri State University, discovered the 43rd Mersenne Prime : 230,402,457-1, which is the largest known prime number . This new prime is as long as 9,152,052 digits. Check out this new largest prime number from here . Still now, many mathematicians all over the world are trying hard to find out a larger prime! Even, you can win $100,000 finding a larger prime number from Mersenne.Org .
357686312646216567629137 is the largest Left Truncatable Prime Number, meaning that the number, as well as all the numbers obtained by successively removing the first digit at the left of the number are primes: 357686312646216567629137, 57686312646216567629137, ... , 9137, 137, 37 and 7 are all prime. Similarly, 73939133 is the largest Right Truncatable Prime Number in decimal, so that 73939133, 7393913, 739391, ..., 739, 73 and 7 are all prime. |
