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.
