The school has 14 boys and 10 girls. If 4 boys and 3 girls drop out, how many boys and girls are left?
There are 14 boys - 4 boys = <T>subtract(14, 4)=10 boys left.
There are 10 girls - 3 girls = <T>subtract(10, 3)=7 girls left.
In total there are 10 boys + 7 girls = <T>add(10, 7)=17 boys and girls left.
