Actually you already know it's 54 because you did the math from the second picture countless times in your head so the connection in your brain is faster.

Before 6, it's 5. And to make 10 with 6, it's 4. So 54.

What I do with 9 is I take the number under the multiplier (so 5 here) and add what's missing to get 9,so 4. If you ask me 9x7 I immediately think about 6 and then it's easy, so it's 63 and boom

And then here I am doing 6*6 + 3*6 because I'm an idiot and can't compute
