This is my favourite Kata so far, nice one, linear algebra ftw

fixed

Would you repost your solution please?
There is no solution that appears for me

typo: failing Python test says "should rerurn"

Merged

python new test framework is required. updated in this fork

very nice kata!

Unpublished, waiting for the new COBOL tests framework.

COBOL translation

Tests in R are disproportionately harder than in other languages. 1000 tests make fail many approaches valid elsewhere (~100 tests in Python and NASM, ~30 in JS and C...).

Honestly, great Job.

good fun kata!.

Ruby 3.0 should be enabled, read this to learn how to do it

Please organize the structure of test fixture as following (although it has been mentioned in the attached link, I'm repeated here again)

describe "<This message should describe the categories of test groups inside this block>" do
  it "<A short message describing this test group>" do
    expect(...).to eq(...) #Assertions
    #Or Test.assert_equals(user_response, reference_response)
  end
end

thanks for making it understandable

not clear instructions ...

The description says:

For a case like "2 2 4" - when multiple variants are possible - choose the first possible operation from the list (in this case "addition")
