Here is a neat math trick I learned from Alex Bellos’ book “Here’s looking at Euclid”. The Trick Start by picking any three digit number where the first and last digits differ by at least two. For example 421. The revers it’s digits … 124 Subtract the smaller number from the bigger number 421 – 124 = 297 Reverse this result and add the two numbers … 297 + 792 = 1089 Now try this with any other three digit number whose first and last digits differ by at least two … say 519 reverse of 519 is 915 difference…
