So, if I write a check for \$120.45 and I write the amount as: . one hundred twenty and........45/00 . Is the check valid, since I expressed it as a division by zero, which is mathematically meaningless? . Last edited by dgodave; 08-15-09 at 01:32 PM.

Good point. I dont even know what that means. Perhap its even more meaningless than division by single zero.

Any human being who hppens to look at it will not care about the legal niceties - they are a "production unit" and are under the gun to get the work out the door.
