There are 76 cars in the car park. 18 more cars go into the car park. Then, 35 cars go out. How many cars are in the car park now?

The bar model shows there are 76 cars and 18 more cars going to the car park. 35 cars go out. We have to calculate how many cars are in the car park now. So first, we can calculate how many cars there were in the car park. Before, 35 cars went out. So first, we need to add together the number of cars that went in, 76 and 18. We could calculate 76 plus 20 really easily. 76 plus 20 is 96. We rounded 18 to 20 by adding two to 18. So we added two to many. So now, we need to take that two away. 96 take away two, 96 take away two is 94. So there were 94 cars in the car park.

And we know that 35 cars went out of the car park. So we need to calculate 94 take away 35. First, we could take away the 30. 94 take away 30 is 64. Then, we need to take away the five. 64 take away five is 59. There are 59 cars in the car park now.

First, we added together the number of cars in the car park by adding 76 and 18, which gave us a total of 94. Then, we took away the 35 cars that left to give us a total number of cars in the car park now of 59.
