Problem: what is the difference between the largest number and the least number written with the figures 3 , 4 , 7 , 0 , 3 ?
Rationale: "74330 largest 30347 smallest - - - - - - - - - - - - - 43983 answer : c"
annotated_formula: subtract(add(add(add(multiply(multiply(3, const_100), const_10), multiply(0, const_100)), multiply(4, const_10)), 7), add(add(add(const_1000, multiply(4, const_100)), multiply(0, const_10)), 3))
