I can't tell you what 6x9 is. But I can tell you what 9x6 is. I always turn that one around. My mind immediately jumps to a visual 60 coz 10x6 is super easy of course and subtracting 6 from it is easily 54. Similarly 8x7 I can't tell you but 7x8=56 in my brain feels like a little "rhyme" I just need to repeat and I have the answer. That's also how I remember (somewhat) arbitrary passwords. If it "flows" well almost like a rhyme and can be typed fluently I'll remember. Actual arbitrary ones don't work as well.
