...or actually, it doesn't. A few fans found figures that just didn't add up. Here they are.
Steven J Pemberton deserves full credit for this finding. "My bank helpfully reminds me when it's time to pay my bill, and normally has no problem getting it right. But this month, the message sent Today 08:02, telling me I had to pay by tomorrow 21-Nov was sent on... 21-Nov. The amount I owed was missing the decimal point. They then apologised for freaking me out, but got that wrong too, by not replacing the placeholder for the amount I really needed to pay. "
Faithful Michael R. levels a charge of confusion against what looks like.. Ticketmaster, maybe? "My card indeed ends with 0000. Perhaps they do some weird math with their cc numbers to store them as numerics." It's not so much weird math as simply reification. Your so called "credit card number" is not actually a number; it is a digit string. And the last four digits are also a digit string.
Marc Würth,
who still uses Facebook, gripes that their webdevs
also don't understand the difference between numbers and digit strings.

Self-styled dragoncoder047 is baffled by what is probably a real simple bug in some display logic reporting the numerator where it should display the denominator (2). Grumbles DC "Somebody please explain to me how 5+2+2+2+2+2+2+0.75+2+2=23. If WebAssign itself can't even master basic arithmetic, how can I trust it teaching me calculus? "
Finally Andrew C. has a non-mathematical digit or two to share, assuming you're inclined to obscure puns. "As well as having to endure the indignity of job seeking, now I get called names too!" This probably requires explanation for those who are not both native speakers of the King's English and familiar with cryptographic engineering.
