About This Design

Friends Don't Divide by Zero Postcard

Friends Don't Divide by Zero Postcard

Friends don't let friends divide by zero. Disrupting the fabric of spacetime and imploding the universe is just bad business for everyone. Pretty irresponsible. Great gift or tshirt for the scientifically and mathematically conscious.
