- Amazingly you can get the sum of hundred using all digits in succession in various ways. (A) 12+3-4+5+67+8+9 = 100 , (B) 123 – 45 – 67 + 89 = 100 ,(C) 123 + 4 – 5 + 67 – 89 = 100 ,(D) 123 – 4 – 5 – 6 – 7 + 8 – 9 = 100 , (E) 1 + 23 – 4 + 5 + 6 + 78 – 9 = 100.
- The fact is 2,520 is the smallest number that can be exactly divided by all the numbers 1 to 10.
- 142857 is an amazing cyclic number, i.e., its digits are rotated around when multiplied by any number from 1 to 6.
- 1729 is the only number that is the sum of 2 cubes in two different ways. 10^3 + 9^3 = 1729 & 12^3 + 1^3 = 1729. It is named after Ramanujan, an Indian mathematician.
- This amazing equation uses all the digits from 0 to 9. 69^3 = 328509.
- The amazing number 1274953680 uses all the digits 0-9 and you can divide it exactly by any number from 1-16.
- There is a way of amazingly writing 1 by using all ten single-digit numbers only once: 148/296 + 35/70 = 1.
- 1^2 + 2^2 + 3^2 + 4^2 + 5^2 +… +22^2 + 23^2 + 24^2 = 70^2 Amazing !
- The fact is that the product of any four consecutive numbers is divisible by 24!
- Multiply 37,037 by any single number (1-9), then multiply that number by 3. Amazingly every digit in the answer will be the same as that first single number.e.g. 37,037 *2*3 = 222,222.
- The amazing fact is that there are just four numbers (after 1) which are the sums of the cubes of their digits. These are 153 , 370 , 371 & 407.
- If you multiply 21978 by 4 it amazingly turns backward. 21978 x 4 = 87912.
- 1089 multiplied by 9 amazingly gives an exact reverse: 9801. This also works with 10989 or 109989 or 1099989 and so on.
- 13^2 = 169 and if you write both numbers backward you get 31^2 = 961. This also works with 12 because 12^2 = 144 and 21^2 =441.
- 1 ÷ 37 = 0·0270270270… and 1 ÷ 27 = 0·0370370370. Amazing coincidence !
- 1/1089 = 0·00091827364554637281 . Amazingly this is a table of nine.
- To multiply 10,112,359,550,561,797,752,808,988,764,044,943,820,224,719 by 9 you just move the 9 at the very end up to the front. Amazingly it’s the only number that does this.
- 3,608,528,850,368,400,786,036,725 has 25 digits and divides by 25. But amazingly if you just take the first n digits, the result will divide by n. For example, 360852 are the first 6 digits and 360852 divides by 6.
- Amazing fact is that any 2-digit number multiplied by 11 is a 3-digit number where the middle digit is the sum of other two, like: 21 × 11 = 231 (2+1=3) ,13 × 11 = 143 (1+3=4) ,44 × 11 = 484 (4+4=8) … etc.
