Magic Number
1089 is known as the magic number. Here's why:
Choose any three-digit number different: for example, 875.
Now write this number backwards and subtract the smaller more:
875-578 = 297
Now reverse this result and also do the sum:
297 + 792 = 1089 (the magic number)
Warning: before you send us an e-mail saying that does not work with certain numbers, remember that three digits must be used in the calculation. example:
574-475 = 099
099 + 990 = 1089
