â€œAm I supposed to factor for X,â€ the kid asks. His math tutor replies, â€œUmâ€¦ I donâ€™t know.â€ I really hope this kidâ€™s parents are getting a discount rate.

**Math is hard, kid.**

Based on the kidâ€™s age, Iâ€™m guessing this isnâ€™t differential calculus happening here. Iâ€™m also guessing Math Tutor Guy should know whether or not the kid needs to factor for X.

Considering Math Tutor Guy is supposed to know more than his clients, maybe he could at least go through the motions and say something like, â€œYou need to find the differential for the tangent before solving for the integral. *Then* you can factor for X.”

Either way, I see a promising future in the food services industry for Math Tutor Guy. Those burgers wonâ€™t flip themselves, you know.

The last time I witnessed a math difficulty like that in a coffee shop was when my total was $4.77, and I gave the cashier a $5 bill and two pennies.

Yes, but did you remind them to factor for X?
