There are four frogs in a lake, and
then three frogs jump away. How many are left?
In this problem, we begin with four
frogs in a lake. Three of the frogs jump away. How many frogs are left? We started with four frogs, but three
of them jumped away. So to find out how many frogs are left,
we need to take away three frogs from our four frogs. Four take away three leaves us with one
frog. If we take three from four, we get
one. If there are four frogs in a lake and
three frogs jump away, there will be one frog left.
