50 + 8 = 58, as does 29 + 29 or 41 + 17.
58 + 7 + 7 = 72
58 + 37 = 95

71 degrees. Add 58 plus 13. If you look at it on a thermometer 13 is well, 13 away from zero and 58 is 58 away from zero in the opposite direction. To go to negative 13 from positive 58 you have to go 58 degrees to get to zero and then 13 more to get to negative 13. So 58 plus 13 is 71.
