You're a math geek and proud of it! So go ahead and show your love of math with this tee that has formulas written in black all over the front of this shirt. Looks like you couldn't wait to write them all out so you just used your shirt, but be sure to show your work! This Old Glory design is printed on a polyester women's tank top. The dye sublimation printing process creates slight imperfections that are unique to each garment.
