How can you compare an INT to many other INTs?

Well,

int a = 20;
int b = 30;
int c = 40;
int d = 50;

if (a > b,c,d)

how would i approach this, i have no idea i fail at every turn, its been hours

If all you want to know is if the number x is greater than the other numbers, you could either compare them explicitly like if(x>b & b>c) or use something like if(list.All(x=> a > x)) as mentioned above. If you have many numbers and all you want is the higher number, you could sort the list using a quick sort that could be efficient and get the first item.

It's a bit different if you need to compare them and get different comparissons then probably the easiest thing is to loop through the list.

Non-LINQ example:

if (Math.Max(a, Math.Max(b, Math.Max(c, d))) == a)
{
}

Put them all in a list and do this:

if(list.All(x=> a > x))

Or in one line:

if(new List<int>{a, b, c, d}.All(x=> a > x))

EDIT I changed the Max() to All(x => a > x) because the a > x will not return a true when a == x whereas Max() will do that.

If there is a short quantity of numbers, you can simply use the boolean logic:

if (a > b && a > c && a > d)
{
}

If you don't know in advance the quantity of numbers, what about creating a collection and compare the first number to the numbers from the collection through a loop?

var numbers = { 30, 40, 50 };
if (!numbers.Any(c => 20 <= c))
{
}

You can put them in an array:

int a = 20;
int[] others = { 30, 40, 50 };

if(others.All(o => a > o))
{
    // do something
}
