Yes it is possible in another number system but more than 9, in 16 also does not work

You have to try other non-standard ones, starting with 11.

7,9 + 9,1 + 13

Perhaps it is a test for schizophrenia. The instructions say "using these numbers". Obviously a comma is a separator between numbers when listing them, not a decimal separator. If it said "using the signs below", then you could use 7,9 and 9,1. If 7.9 and 9.1 are used, then the test instruction is not fulfilled - signs are used, not numbers.

The correct answer is "no solution".

I looked and looked, and did not find the solution - for me the separator sign for decimals is a dot. And my wife looked and almost immediately gave me the answer. She is not a programmer - she is a doctor, but she loves mathematics, and does not take conditions of the task strictly - numbers, signs - all the same - it was necessary to substitute the values from the list below - she found and substituted.

It's a way of thinking...

Yeah, she called me a nerd too... :))

I looked and looked and did not find the solution - for me the separator sign for decimal fractions is a dot. And my wife looked, and almost immediately gave me the answer - she is not a programmer - a doctor, but she loves mathematics, and does not accept the conditions of the problem strictly - numbers, signs - all one - it was necessary to substitute the values from the list below - she found and substituted.

Even a comma, but then there should have been a semicolon between the fractional numbers.

I say it's a way of thinking. Some people care about delimiters, while others just solve a problem from a given set of numbers/symbols. I have not solved it - there are a lot of barriers - there is no dot as a fractional part separator, there is no semicolon between digits denoting numbers... In general, everyone thinks within their own limitations and horizons.

For some people a line on a piece of paper is just a clumsy line, but for a child who has drawn it carefully with a pencil it is a road - the whole world...
