Simple Math

Do you remember I mentioned Roberta?

Well the other day, Roberta was asked to make corrections to a very basic math problem.  She has administered this test a million and a half times.  Well because she only has 2 brain cells to begin with, on this particular day these 2 brain cells were clearly not communicating with one another.  

On this particular test she needed to round the test result number to the hundredth place.  Well she actually rounded it to the tenth place and when her error was called out, I shit you not, this was her explanation:

"Oh well I thought I was supposed to round to the hundredth place and I know I've done it many times before so I know what I'm doing so the hundredth place is the digit after the decimal point so I don't know what I did wrong"

No joke.  I do not exaggerate.  And yes, she spoke it that way fully equip without punctuation.  And if you were present you would've witnessed her head bobbing side-to-side as she said this.

Clearly I must've missed something in the first grade because I thought the digit after the decimal point is the tenth place.  Guess I was wrong....
