I think a little more of a description would be good. Also maybe make it just a tad harder. The test cases were very good.

too easy, needs a twist, even for an eight

Never type checks arguments

There is no point to this kata. It is too easy to be useful.

extremely simple

Reasonable for extreme beginners. As others pointed out, it's only useful for people learning syntax or programming for the first time.

This kata is basically pointless. The little "prove you know your language" thing that codewars does when you sign up us harder than this.

The name isn't even capitalized, the description is grossly lacking. This is an excercise in gross simplicity that doesn't teach anything.

Too easy

May be worth making it explicit that the parameters will always be ints (or passing strings to see if people are checking for type).

This kata is way too easy. There isn't any challenge.

As it stands the current kata is way too easy. It needs some test cases that will make the user think and also needs to have a better description

For this to be any sort of challenge above very-beginner level, it needs a real challenge: something unexpected or weird that the warrior will have to deal with. In its current form, it is far too simple.

Since there is a bit more complicated test, for you to be able to join this community, i believe that this 'kata' has no place here, in its current form.

If you want to make it a little bit more interesting for the warriors, you can either disable the "+" symbol(not much of a challenge, but still- won't be THAT basic :D) or make the warriors add strings and lists too ;)

Way too easy. The instructions are unclear as well.
