Tell us what’s happening:

Your code so far


var a = 3;
var b = 17;
var c = 12;

// Only modify code below this line

a = a + 12;
b = 9 + b;
c = c + 7;

Can you explain what did you understand from the examples given. I will be able to help you out more.

You simple just do this:

//This is your given code
var a = 3;
var b = 17;
var c = 12;

a = a + 12;
b = 9 + b;
c = c + 7;

If you read the explanation

to add 5 to myVar . Since this is such a common pattern, there are operators which do both a mathematical operation and assignment in one step.

Which means you simply grab your ‘a, b, c’ from the example and do this:

a += 12;
b += 9;
c += 7;

And this is the same thing.

So in the example
myVar = myVar + 5;
becomes:
myVar += 5;
when we have:
b = 9 + b;
it’s the same
b + = 9;
we can even make our own
x = 11 + x:
x +=11;
