About This Design
2 + 2 = 10 T-Shirt
There is an arbitrary number of numbering systems.  The most familiar is Base-10 (decimal).  Computer science uses Base-16 (hexadecimal), Base-8 (octal), and Base-2 (binary).  Base-4 consists of numbers from 0 to 3.  Adding 1 to 3 give 0 plus "carry the one", i.e. "10".  Adding 2 to 2, gives the same result: 10.  Further cement to your family and friends that you are truly a geek, by showing that you can do math in an arbitrary numbering system.

They turned out exactly as we had hoped and we looked good even when we didn't bowl well. The printing was perfect and you can only see 9 pins on the shirt(the 5 pin hidden behind the headpin) which worked for us as we bowled in a 9 pin No-Tap league.

The shirt I ordered was too small. I contacted Zazzle and they replaced it with a larger size. Very happy.

Great t-shirt!!! Quality is amazing and the colours are vibrant. Exactly how described!!! Can’t wait for my daughter to ask and give it to her confirmation sponsor. It’s also came earlier than I expected. Colours were exactly what I expected. The quality is amazing. The images couldn’t be any better. I’m very happy with his product and highly recommend it.
