Problem: what is the sum of all 3 digit integers formed using the digits 34 and 5 ( repetition is allowed )
Rationale: n = 3 * 3 * 3 = 27 = ( 555 + 333 ) / 2 = 444 sum = number of integers x average value n * = 27 * 444 = 11988 answer = d
annotated_formula: multiply(multiply(add(add(const_100, const_10), const_1), add(add(3, 5), const_4)), power(const_3, const_2))
