Question

There are 20 penguins on an iceberg.

9 penguins jump in the water.
8 penguins move to an island.
How many penguins are still on the iceberg?

Answer 1

3 penguins

Explanation:

You start off with 20 penguins.

Since 9 penguins jump in the water. You are subtracting 9.

20-9=11

Then, 8 penguins move on to a island so subtract 8 from 11.

11-8=3

Final answer

3

Answer 2

3 penguins

Explanation:

9+8= 17

20-17= 3
