Tell us what’s happening:
Instructions
Convert the assignments for a, b, and c to use the += operator.
I have written the code, as it’s told to do, but I receive this message
"You should use the += operator for each variable"
Your code so far
var a += 12;
var b +=9;
var c += 7;
// Only modify code below this line
a = a + 12;
b = 9 + b;
c = c + 7;
var a += 12;
var b +=9;
var c += 7;
