Friday Puzzler -- Dot Matrix
Alex Y
I typed a valid equation, but when I printed it on my old dot matrix printer, the printer either added or deleted one dot, coming out like this. 
What was the valid equation I had typed?

This seems to be missing something that would indicate an arithmetic mean: (72+70)/2=71.

Nothing to do with the mean

My printer added an extraneous dot. Remove one dot to make this a true equation.
