How to Compound Assignment With Augmented Addition

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;

Link to the challenge:

What problem are you having? The code you have there has no modification.

“Convert the assignments for a , b , and c to use the += operator.”

i don’t understand that why

Like stated in the challenge having myVar = myVar + 5; is the same as having myVar += 5, you just have to change a, b and c to +=

please show me the solution
