Something you're just good at with minimal effort and/or you learned much more quickly than average.
For me, it's paper snowflakes. My brain just seems to effortlessly figure out what cuts to make to the paper wedge to make it turn out exactly how I want it. Largely useless, but good fun and was a much-needed ego boost when I was a kid :]
Please could you explain a bit more about the process you describe, above? Maybe with some simple examples? I'm woeful at maths but really good with mechanical and physical problems. If there's a way I can improve upon the former, I'd love to try.
Thanks in advance!
C = BxA
Move A underneath C and swap the equality
B = C/A
A lot of algebra is spatial manipulation.
