43. Take the number 7654 and reverse the digits to form the number 4567. Now subtract the smaller number from the larger one (7654 – 4567 = 3087). Try
this for other four-digit numbers whose digits are consecutive integers
written in descending order (largest to smallest). Make a conjecture
from your observations.
