Thread: With three fives make 6

1. With three fives make 6

Use three 5s and no other digits to make an expression that equals 6.

You can use these only:

parentheses, +, -, /, *, regular factorial sign, square root symbol (or "sqrt"), decimal point (no repeating decimal use), concatenation of digits

I'll start if off:

5 + 5/5 = 6

I am looking for at least three other primitive* solutions.

* For example, "5/5 + 5 = 6" would not be another primitive solution.

**5 + (5 - 5)! = 6

5.5 + .5 = 6
**

3. Re: With three fives make 6 Originally Posted by Debsta **5 + (5 - 5)! = 6

Those two solutions are two of the remaining three solutions that I also have.

Here's another one:
**5 + .5 + .5 = 6, I'd say that is different to 5.5 + .5**
**5 + (5/5)!**

The above would be my third solution. I agree it is
different compared to the one next to it.
