How Many Oak Trees Were Planted Today?

Explanation: To find out how many oak trees the workers planted today, we can subtract the initial number of oak trees in the park from the final number. So, 58 - 36 = 22. Therefore, the workers planted 22 oak trees today.

Further Explanation:

The workers would have planted 22 oak trees. All you have to do is subtract the total number of trees from the trees they had before they planted the new ones. In this case, 58 - 36 = 22, so the workers indeed planted 22 oak trees.
