In case you have serious problems with mathematics and can’t do a simple 45*21 multiplication, maybe the Calculator Belt Buckle can help you out.

Calculator Belt Buckle

The image and name of the gadget say it all, so I won’t bother to write a witty description, but knowing that you can always count with a calculator placed on your belt buckle is always good. The Chrome Calculator Belt Buckle is very, very cheap - it only costs $10.

You can easily attach this buckle the correct way to have a stylish math buckle or flip it upside down goofy style for easy use so you can see exactly what your doing.
