The "Arithmetic Word Problems" exercise accepts incorrect answers. Question: "Daniel bought 5 saws, all costing the same amount, from the hardware store. He also bought a hammer for 6 dollars. He spent a total of 56 dollars. How much did each saw cost?" The correct answer, of course, is 10 dollars. But 10.50 is an accepted answer. This seems to happen every time this particular type of problem is presented in this exercise.
