I can and will work at maths until I have the right answer.
If you have the time then I have the patience.
I am better at mental arithmatic than my mother and sister, just because I have deliberately learned my "number-bonds". I have specific tools. If I had to sit down and do it in the way I was taught, I would come up with the incorrect answer pretty much every time, but I can work around that.
Oh and my division is tricky.
I'm better at calculating percentages than some people I know. Not on the Cellar of course, just in general life. It might take me a while, but I can come up with something to prove one menu discount option is better than another. But I need a pen and paper.
I can work out a 10, 15 or 20 % tip though
No-one will ever love me for my maths skills.
But I can proof-read like a demon.
Again, not here, because it's not really necessary for typos and occasional errors (in my posts). But it is something that comes naturally, as opposed to having to sweat over it.
I'm in no way an intellectual.
But an innate maths ability does not feature in that self-reckoning.
