I guarantee you that you've memorized these tables, you just didn't put any effort into deliberately doing it. It happened accidentally as you used numbers frequently.

Of course, maybe I'm wrong. Maybe you DO need to use a calculator to quickly tell me what 8 * 6 is. But I would be highly surprised if you got a degree in math and still needed a calculator for that.

For 8*6? I definitely don't know either of the 8 or 6 tables by memory.

I of course know how to figure it out. Let's see my instinct might be to do 8x2 first because I do know most of the 2s. Then 16x3 I can do in a few steps of addition. 20+12+16 then 48

And yes then I checked on my calculator because I'm posting this online and don't want to look like an idiot.
