+= increments variables by the given number. Say you have a variable X that is 4,
X = 4
X += 2
X is now 6.
The other ones are just different math operators, i.e.
*= is multiplication
/= is division
-= is subtraction

X += Y and the others are just a shorter form of writing
X = X + Y
If you only need to increment by 1 each time, you can use X++ as opposed to X = X + 1.
In C are those shortcuts also better for the performance (if the compiler is halfway decent) because it can tell the CPU that it only needs to look up X once and not twice. But I don't know if the UnrealScript compiler/interpreter makes use of such kind of optimization.

x+=2 is simply short for x=x+2
