because, 1/1 (equivalent to 1) * 584/25 = 584/25.

The pi button is in the top-left corner directly to the right of the 2nd button on the web2.0calc calculator.

We know that 3 can be represented as 3/1.

5/3 / 3 = 5/3 / 3/1.

We also know that you can multiply the dividend by the reciprocal of the divisor.

5/3 / 3/1 = 5/3 * 1/3.

Now we can multiply what's on top by what's on top, and what's on the bottom by what's on the bottom.

(5 * 1) / (3 * 3) = 5/9.

If you are trying to represent a date, including the year, with one digit, you would need a number system with infinite characters, because each new day would call for a new character. Now, if you wanted to represent each day of the year with a number, you would only need 366 characters, as that is how many days are in a leap year.

It is dependant on if the number "2" is exactly 2 or not. It could, in fact, be rounded from a number ranged from ~1.50 to a number ~2.49, in which case "two plus two" could literally equal a number from 3 or 5.
