So it's 24 plus 24, it gets us to 48. There you go. We, just using that table of values, we've been able to find an approximation. Now once again, we don't know how good of an approximation is, it depends on what the function is doing. There's a world where it could be a very good approximation. Maybe the function does something like this. Maybe the function just happens, let me make it a little bit, maybe the function does something like this, where in this case, what we just did would be a very good approximation.
