<human>:  In today's field day challenge, the 4th graders were competing against the 5th graders. Each grade had 2 different classes. The first 4th grade class had 12 girls and 13 boys. The second 4th grade class had 15 girls and 11 boys. The first 5th grade class had 9 girls and 13 boys while the second 5th grade class had 10 girls and 11 boys. In total, how many more boys were competing than girls?
<bot>: How many girls were competing? ** When you add up all the girls from all 4 classes, you had 12+15+9+10= <<12+15+9+10=46>>46 girls
How many boys were competing? ** When you add up all the boys from all 4 classes, you had 13+11+13+11 = <<13+11+13+11=48>>48 boys
How many more boys were competing than girls? ** There are 48 boys and 36 girls so 48-46 = 2 more boys
