While Greg was camping with his family for a week, it rained for 3 days. When he looked at the weather records, he saw that the amount of rain was 3 mm, 6 mm, and 5 mm on the three days. During the same week, it rained 26 mm at his house. How much less rain did Greg experience while camping?
While camping there was 3 + 6 + 5 = <<3+6+5=14>>14 mm of rain in 3 days.
Greg experienced 26 – 14 = <<26-14=12>>12 mm less rain at the campsite.
