An ant is on top of a tree 23 meters tall, directly above her home, which is 0.3 meters below the ground. What is an expression that represents the difference in elevation between the ant and her home?

To find the difference in elevation between the ant and her home, we need to subtract the height of the tree from the depth of her home.

The height of the tree is 23 meters, and the depth of the home below the ground is -0.3 meters (since it is below the ground level, we use a negative value).

Therefore, the expression that represents the difference in elevation between the ant and her home is:

23 - (-0.3) = 23 + 0.3

Simplifying this expression gives us the final answer:

= 23.3 meters

So, the ant is 23.3 meters above her home.

23.0 + 0.3 =
