Question

Each car has 4 wheels. How many wheels do 7 cars have?

Answer 1

7 cars. 4 tires each times 7 cars equal 28 tires

Answer 2

The total number of wheels is the addition of all of the wheels in the cars.
4+4+4+4+4+4+4
or 4 wheels for each car
That can be simplified into 4 x 7 because 4 is multiplied 7 times.
The total number of wheels is 4 x 7 or 28 wheels in all.

Answer: 28 wheels

Hope this helps :)
