Set by Colin Beveridge
A pandigital sum is an addition that uses each of the digits from 0 to 9 exactly once, and no number within the sum starts with a zero. For example, 4927 + 86 = 5013 can be represented as ABCD + EF = GHIJ, where each letter is a different digit.
There are 36 pandigital sums of the form ABCD + EF = GHIJ. Can you find one where GHIJ = 2034?
There are 96 pandigital sums of the form ABC + DEF = GHIJ. How many can you find where GHIJ = 1089?
There is one pandigital sum of the form ABC…
