there are 8 on the bus.the bus driver drops off 3 children and picks up 7 more.how many children are on the bus now?

Answer 1

Initially, there are 8 children on the bus. The bus driver drops off 3 children, which leaves:

8 - 3 = 5 children.

Then, the bus driver picks up 7 more children:

5 + 7 = 12 children.

So, there are now 12 children on the bus.
