I have encountered the question
"What is the sum of all the (distinct, positive) prime factors of 99?" but I have no idea what "prime factors", "distinct" and "positive" are. Its not that I'm *terrible* at maths, its just that I've done most of my math problems in Polish. Help me please!

TopNewestHi. Distinct means different. You can't repeat the same number. Distinct = 1,2,3,10,14 Not distinct = 1,1,2,3,10,10,14 Prime numbers are 2,3,5,7,11.... Factors are things that the number is divisible by. Factors of 24=1,2,3,4,6,8,12,24 Prime factors of 24 are 2,3 Positive means above zero. 1, 5 and 10 are positive but -3, -2 and -59 are not/ – Shubham Bhargava · 3 years, 9 months ago

Thanks - but I'm not sure I understood the thing with distinct and positive.Log in to reply

Distinct numbers are different from each other. 1,2 and 3 are different but in 1, 1, 2, 3 are not different. 1 is there two times – Shubham Bhargava · 3 years, 9 months ago

In this problem, "distinct" means just that they want you to add each factor only once.Log in to reply

Okay, I understand, thank you!Log in to reply

Distinct numbers are a set of numbers where they are all different. e.g. {1,2,4,5,8,6,3,9} Prime numbers are numbers which can only be divided by 1 and the number itself. Composite numbers are the opposite of primes, meaning that they can divided by other numbers. e.g. {2,3,97,11,17,67} are prime and {4,6,8,9,96,85}. 1 is not prime or composite. Positive numbers are numbers bigger than zero. e.g. {1,2,5,6,34,64,543} Hope it helps. – Sharky Kesa · 3 years, 9 months ago

If \(x\) is positive, then \(0<x\).

If \(y\) and \(z\) are distinct, then \(y\not= z\). – Vincent Tandya · 3 years, 9 months ago
