Can you solve seven times nine without tables or a calculator? Hold up ten fingers. Count from the left. Fold down your seventh finger. Look: six fingers left, three right. That finger isn't just counting-it's encoding the answer: the left side gives tens, the right side gives ones. So seven times nine is sixty-three. Check it: six tens plus three equals sixty-three. Yes-you can solve it in seconds: use the finger pattern, then check the answer in your head.
