Correct layout of e^/LN/10^/LOG?

Base 2 logs are also great for teaching about what a log actually is. I managed to ride with my son to the end of his high-school maths and help him with it. With base 2 logs, the graph is nice and easy to draw by hand on a piece of paper., using an x scale from say 0 to 8, and y from say -3 up to 3. eg

0.125, -3
0.25, -2
0.5, -1
1, 0,
2, 1
4, 2
8, 3

Having seen that, then log10 is easy to grasp and then with a couple more concepts, base e.

And then I recommended that he go and explain that to a friend, to cement the understanding
