My husband thinks I'm a little strange. Apparently, I have no talent for anything number-wise, so math, geometry, algebra, all those... make absolutely no sense to me. So, to compensate, I try to make "handles" for numbers so I can remember them better.
For example, a friend's address number (one of those crazy long ones): 10743. If you start out with ten (because 10 just makes sense - everything goes to 10), then you subtract 3, you get 7. If you subtract 3 more, you get 4, then subtract one more, you get 3.
(Tim groans as he reads this over my shoulder).
Recently, I was supposed to remember the number 4890 to remind Tim in case he forgot it. (Small chance of that - my husband's a whiz at numbers). Tim told me the number. I thought for a minute, then said, "Okay, I've got it."
"I'm afraid to ask. But how are you remembering it?"
So I explained. "90 is double 45. 45 is half of 90. Add 3 to 45 because I have 3 kids, which gives you 48. So 4890."
Tim asked, "How do you remember 90 in the first place?"
"Because 90 minutes is the length of most normal-paced movies."
And he thinks numbers aren't my strong point. *Pfff* :)
