Question

At 8:00 am the temperature was 3 degrees below zero. By 9:00 am the temperature had gone up 6 degrees, but by 10:00 am it had gone down again 4 degrees. What was the temperature at 10:00 am?

Answer 1

So the temperature starts at -3 then you add 6 because the temperature went up 6 degrees and then you subtract 4 degrees because the temperature dropped by 4 at 10:00 am. So -3 + 6 - 4 = ?
