# what's mean x -= y += 9

You can use multiple assignment operators in one line, such as x -= y += 9. Whether it is equal to x=x-9 &y=y+9 & x-9=y+9 ？？？

x = x-(y+9) is what i would say

This doesn't exactly answer the question but I have to say it: You can write it this way but it's bad practice. Also bad practice is nested ternaries. Generally when we write code we want to write it in a way that is easily understood. e.g. If you look at a well written piece of code 1 year later you can understand what's happening in the code fairly quickly and make the necessary adjustments/corrections/changes. If you look at a piece of code that's written like a cipher 1 year later I guarantee you that you'll say: "f
amp;@ this, ill rewrite the whole thing."

Just great answer by Mbrustler . But remember assignment works different depending the language. Like in python x = x + 1 x += 1 Even this have the same result. this two line of codes still works different for python.

Gordie in the last part, x will be assigned to x-y-9 and not x-y+9. But you cleared that in last 2 lines so it doesn't matter 😄

x-=y+=9 means x-=(y+=9) I.e y=y+9 x=x-y

It means y=y+9 x=x-y

Breakdown the string by 'equal' sign. You get x=x-y as there is x-=y; and y=y+9 as there is y+=9 So, substitute and get the final result as follows, x=x-(y+9).

x = x - y, where y = y + 9
