Tommy goes for a run around his neighborhood and decides to calculate how many wheels he saw. All the trucks in his neighborhood have 4 wheels and all the cars in his neighborhood also have 4 wheels. If he saw 12 trucks and 13 cars, how many wheels did he see?
How many vehicles did Tommy see? ** He saw 25 total vehicles because 12 plus 13 equals <<12+13=25>>25.
How many wheels did Tommy see? ** He saw 100 wheels because 25 times 4 equals <<25*4=100>>100.
#### 100
