This is an example of how 0.99999... can equal 1. Strange, but get deeper in these type of equations this makes sense.

One of our members, Alan, could tell you precisely why this happens, but

 

If  you key in (1/3) * 3  the calculator will interpret this as  (1 * 3) / 3  = 3/ 3  = 1

 

However.....if you key in 1/3....you will get the fraction's decimal representation of  .3333...

 

And multiplying this by 3  =  .99999....

 

 

cool cool cool
