Problem: the sum of digits of a two digit number is 8 , the difference between the digits is 6 . find the number
Rationale: "description : = > x + y = 8 , x - y = 6 adding these 2 x = 14 = > x = 7 , y = 1 . thus the number is 71 answer d"
annotated_formula: add(multiply(divide(add(8, 6), const_2), 8), subtract(8, divide(add(8, 6), const_2)))
