Math equals bike repair ability apparently

The other day at work:

Coworker wearing bike helmet enters office.

Coworker: “Hey, are you mathematically inclined?”

Me: “Depends. What do you need done?” (My Math grades were always fine, but nothing amazing.)

Coworker: “My bike chain is messed up. Can you fix it?”

Me: “Uh . . . don’t you mean to ask if I am ‘mechanically oriented’?”

Coworker: “No math . . . means you have good spacial . . . ” *waves hands around*

Me: “I haven’t ridden a bike since I was 12, but I am pretty sure bike repairs and math aren’t related. Maybe the campus bike repair shop can help you?”
