Sometimes people need things spelled out for them, or in this case, drawn out! This friendship algorithm t-shirt is the brainchild of Sheldon, Big Bang Theory's central protagonist! All of that math stuff typically goes over my head, but I think I can follow with this great 100% cotton t-shirt! This is the Women's version of our 'normal' version of the Algorithm shirt, and it is the clear path to decision making when it comes to hanging out with friends. This women's slim cut is more 'form fitting', softer, and for the ladies!
