A (Simple) Arithmetic puzzle

Question

I'm hoping this one was not posted here already, tried to search a bit and didn't find it. It's a really nice brain teaser:

Add arithmetic operators (plus, minus, times, divide) to make the following expression true:

3 1 3 6 = 8.

You can use any parentheses you’d like.

@IAmInPLS Wow, a simple google search. I probably shouldn't have answered this. — bg6471, Sep 2, 2016 at 9:15
Not saying I used google, I'm just saying it was probably too easy and just a math problem? — bg6471, Sep 2, 2016 at 9:16
@Vucko if it makes you feel better, I solved it using the raw power of my brain and notepad.exe because I didn't have a pen and paper — bg6471, Sep 2, 2016 at 9:33
If you had allowed powers then a simple one would have been $$3-1^3+6=8.$$ — ə̷̶̸͇̘̜́̍͗̂̄︣͟, Jul 9, 2018 at 19:05

The solution is,

(3+1)/3*6 = 8

or

(3+1)/(3/6) = 8

I think

(3+1)/3*6=8

works fine
