Mystery of 1089

 

I wrote  this in a forum in different words, but I forgot what the forum is. Now I write here for sharing. Let’s see.

1. Write a three number with each figure different. Example: 345

2. Write the same number backwards 543

3. Now subtract the smaller number from the larger one 543-345=198

4. Turn the answer backwards and add this number to the answer 198+891=1089

You can try with different number and we know that the answer is always 1089.

If your answer should have only two figures, add a zero to make three figures like 99=099

(312-213)    =099

(099+990)   =1089

  5. Berapapun komposisi angkanya akan tetap ketemu angka 1089.
    1+0+8+9=18 –> 1+8=9
    Angka 9 adalah angka yang “unik”
    karena dikalikan berapapun hasilnya tetap 9.

    2×9=18 –> 1+8=9
    3×9=27 –> 2+7=9
    4×9=36 –> 3+6=9
    5×9=45 –> 4+5=9
    … dst.
