When Nathan is cold, he adds an extra blanket to his bed. Each blanket warms him up by 3 degrees. One night, he was cold enough that he added half of the 14 blankets in his closet on his bed. How many degrees did the blankets warm Nathan up?
Nathan added 14 / 2 = <<14/2=7>>7 blankets to his bed.
The blankets warmed Nathan up 7 * 3 = <<7*3=21>>21 degrees.
