Positive number is more specific and accurate than number. I'd have agreed with you. Individual is more specific and accurate than minority. This would be more accurate: OP: The square root of a positive number is a number so the square root of a positive number times another number means it also a number. ME: The square root of a positive number is not just number, it's a positive number. OP: So what. ME: It means we can conclude even more... It means the square root of a positive number times a number is the sign of the non square root number.
