The question is 24 (-6)-1/-5

I don't understand what you do with the 24. I got
-145/-5=29 I multiplied 24 by -6 but I don't think this is right there is a big space between the 24 and the other numbers.

Are those negative signs or subtraction signs?

Just follow BEDMAS, Brackets, exponents, division, multiplication, addition subtraction. Do all those in that order and you should get the right number. It does not matter if you do Multiplication or divsion first.
