Still trying to convince me that my calculator is wrong.

In fact, my calculator just proved that my proof is correct.

Divide 1 by 3, so you get (.3333333...). Don't clear the screen. Multiply that result by 3, and tell me what you get.

Then, remember that basic maths tell us that multiplying (.333333...) by three is the same as performing (.33333333....) + (.33333333....) + (.33333333....). So if the result of multiplying (.333333...) by 3 = 1, so does (.33333333....) + (.33333333....) + (.33333333....) = (.99999999...) = 1.

Go ahead, call all calculators liars.
