Pedro swam some laps in the pool and than swam 2 more

What is your question?

2 + 2 = ?

2 + x

To find out how many laps Pedro swam in total, we need to know the number of laps he started with and the number of laps he completed after swimming 2 more.

Let's say Pedro started with 'x' laps.

After swimming some laps in the pool, he swam 2 more. So, the total number of laps he swam is x + 2.

Therefore, Pedro swam x + 2 laps in total.
