The "Education" section of the OP's profile explains here inability to do an extremely simple math problem.

If you really wanted to have fun with this thread, you could point out that 31 divided into $1150 is 0.0269565217 $^-1, but that would prove that you're both a grammar nerd and a math nerd.

Buy a cheap calculator! ;-)

What does the dollar sign mean?

$^-1 is the plain text way of writing the unit 1/$. Another example would be Hertz = s^-1. It's a really nerdy joke. Sorry.

Doesn't need to buy a calculator. Since she has a computer put the problem in Google search engine.

I was once reviewing a software requirements spec and there was a requirement "...shall be provided at 1 Hz +/- 2 Hz...."

So you'd ask, how could you have a message at one plus or minus two hertz? Think about it. It is possible.

All right, I'll bite. I can see how you can have a period of 1 +/- 0.5 s, but not a frequency of 1 +/- 2 Hz. What am I missing?

Would that be due to a negative vs positive charge? I'm just the amateur, here...
