Just not smart enough to do this math or read the picture .as stated 1/2 inch + dime does not equal 14 mm. 14 mm + dime =1/2 inch .Now to the bigger question - if you've got metric wrenches why not force a 12 mm on it ?
I think you got that backwards, 14 mm plus 1 dime would be closer to 19/32
the two correct answers are 14 mm MINUS 1 dime is 1/2, and 1/2 plus 1 dime is 14 mm
