Math is Hard

At least 1992 Teen Talk Barbie thought so. (Apparently the actual saying is "math class is tough!" But "math is hard!" is funnier and Barbie has a pink convertible and a dream home, so, yeah, I'm going to make fun of her a little bit) Now my math skills can get rusty like anything else if you use them, but in general math is something I "get" and isn't an impossible task.

Unless. It involves the 1990's.
I will explain.

We were going through the materials at work that hadn't circulated in 2+ years. Some stuff was just not on the shelf, some were outdated and some were just plain terrible books that should have never been printed in the first place.

One of the books that circulated in some time was the book Kids, Computers, and Homework. It was the last copy in the entire system, but it was also one of those outdated materials I was referring to earlier. Even with it's awesome graphics I couldn't see a reason to keep it in circulation.

me: When was that published?
coworker: 1995. There probably isn't any relative information in this thing.
me: 1995? ~I quickly do the math~ Yeah, that was nearly 10 years ago. There might have been a few changes in computers in that time.  
coworker: Ten? You mean 20 years ago...
me: ::pause:: ~quickly do the math again~ Shit! You're right. What the hell?! How are the 90s not 10 years ago? Because I remember the 90s and I swear that was only 10 years ago.
coworker:  I don't know, I remember them too.
me: I seriously don't understand how someone born in 1992 can legally drink. Math is hard when it comes to the 90s.
