### MATH (MENTAL ABUSE TO HUMANS)

As I recall, I was completely baffled by 8th grade algebra.  Geometry, which I took in the 9th grade, was a snap!!  Kids who had sailed through algebra couldn't, for the most part, make heads or tails out of geometry.  Go figure!!

If you'll allow me to brag a bit, I am brilliant.  It's just that math is not my strong suit.  That's part of the reason my marriage has lasted so long.  Bud is an accountant/attorney.  I translate things for him & check his spelling & he does all my math.  For those of you who might say we don't have a brain between us, you're wrong; we have one!!  (Also, he gives me his avocados & olives & he gets all my mushrooms.)

 I dug up this collection at Curiosity.com of mathematical cheat codes to divide your multiplication woes in half:

 Figuring out a percentage: You can always switch the numbers when finding a percentage. This trick won't always make it easier, but it's a nice thing to keep in your pocket just in case. So 36% of 50 is the same as 50% of 36: 18. And 18% of 200 is the same as 200% of 18: 36. Now that's a good way to impress a date.

 Multiplying by 11: Multiplying 11 by 1–10 is a piece of cake. But after that, it gets tricky. Here's what you do to multiply it by a 2-digit number, say, 35. First, separate the two digits with a blank: 3_5. Then add them together and fill in the blank: 385. There's your answer! If the digits add up to 10 or larger, just carry the one — it's not 6115, it's 715.
