Benjamin and his family went on a camping trip. When they left home, the temperature was 52 degrees Fahrenheit. When they arrived at their camping site, the temperature was 75 degrees Fahrenheit. How much warmer was it when they arrived at their camping site?
It was 52 degrees Fahrenheit at home and then was 75 degrees Fahrenheit at the camp site. We want to know how much warmer it was at the camp site, the difference between 75 and 52. To find the difference, we subtract 75 minus 52.
Starting in the units place, five minus two equals three, and the tens place seven minus five equals two. The difference between 75 and 52 is 23. And that means the temperature rose by 23 degrees. It was 23 degrees Fahrenheit warmer at the camp site than at home.
