Solve the following exercise:
5+14+5= ? 5+14+5=\text{ ?} 5+14+5= ?
Since the exercise only involves addition, we will use the commutative property to calculate more conveniently:
5+5+14= 5+5+14= 5+5+14=
We will then solve the exercise from left to right:
5+5=10 5+5=10 5+5=10
10+14=24 10+14=24 10+14=24
24
