Problem: evaluate : 60 - 12 * 3 * 2 = ?
Rationale: "according to order of operations , 12 ? 3 ? 2 ( division and multiplication ) is done first from left to right 12 * * 2 = 4 * 2 = 8 hence 60 - 12 * 3 * 2 = 60 - 8 = 52 correct answer b"
annotated_formula: subtract(60, multiply(multiply(12, 3), 2))
