To everybody who enjoys so much reading their own sentence in a 'hot today' thread: You'd learn a lot more if you actually READ a discussion before you just thoughtlessly add another half-baked guess like a dozen people did before you.

Have you tried this in a program? That's the first thing you should do if you have this sort of question.

Try it with -= and =-. Print out the value. Tell us what you found.

Do you know, how a regular assignment works? With only = ? (Sorry I'm a bit like one of these teachers right now who want you to read their mind. ^^)

You can += adds the together and changes value with the sum =+ changes value and makes the number a positive number or =- makes the num a negative number

Int num1 = 4 , num2 = 8 Num2 += num1 Gives output 12 I get that it changes num 2 to num2+num1 but the other way around gives both num1 and num2 the assignment 4

int x = 5 //x is a key 5 is the value x-=2 // same as x=x-2 so x is now 3 because x=5-2=3 y=-2 // y is key with value of -2

Int x =5 , y = -7 y=+x out put for both x and y 5 X=+y out put for both x and y -7 So the only thing I can come up with is it acts as if the + is not there when it is on that side
