looks like you got it solved

arguments: 1, "k", "*"
should return "unknown value"

How to return unknown value in this case, "k" is string and it's converted to double?

While working on this kata, I started thinking about how coding can blend with fitness or health tracking. Has anyone here tried building small side projects like a JavaScript function to calculate calories burned or track daily activity levels?
I’ve been exploring similar ideas lately and even came across a few helpful examples on https://ipptcalculators.com/, it’s interesting how simple tools or calculators can make real-life applications of code more practical.
Curious to hear if anyone else has experimented with JS in this space.

Handling addition, subtraction, multiplication, and division is a great way to practice fundamental JavaScript operations. It's concise yet versatile for beginners.

I like how these challenges show that there’s never just one right solution in coding, everyone has their own style and sometimes a shorter solution isn’t always the clearest.

numbers can be floats!! All solutions that assume they are int in this kata are wrong.

following the instructions and taking some help from AI i am able to create https://easygradercalculator.com/. EVeryone have a look and levae your feedback on improvement areas as well.

Bloated premise imo.

This looks like a duplicate of the Basic Calculator kata.

Java translation

This is the first time I'm writing a Java translation for a kata, so any feedback is welcome.

JavaScript (possibly others)

fixed / random tests should have a test like (5, 5, '-') which should return the calculation of zero, otherwise incorrect solutions like this solution can pass the kata
