Step-by-step explanation:

Given:

Hunter and Logan built small sand towers on the beach.

Hunter built 20 towers, and Logan built 9 towers.

Then, the ocean water came up and knocked down 6 of the towers.

Question asked:

How many of the boys' sand towers were left standing?

Solution:

Number of towers made by Hunter = 20

Number of towers made by Logan = 9

Total towers made by both = 20 + 9 = 29

Number of towers knocked down by the ocean water = 6

Remaining number of towers = 29 - 6 = 23

Thus, 23 sand towers of the boys were left standing.
