Tell us what’s happening:
Sorry, I’ve no solution to this task. Can someone help me or let me know, ho to solve this.
Your code so far
var a = 3;
var b = 17;
var c = 12;
// Only modify code below this line
a = += 12;
b = += 9;
c = += 7;

Link to the challenge:
You need to replace the “=” with “+=”. Like this:
a += 12;
thks for your reply. zdflower, but I#m afraid I#m still don’t know the answer to that, I wrote:
a += 12; b+= 9; c += 7; is that right? can you confirm that pl? Thks for help, I think …I’ve used one “=” twice.
Yes it’s ok.
a += 12 is another way to say
a = a + 12. Like "add 12 to the value of ‘a’ and then assign the result to ’ a’’ .
Where have you used “=” twice?
There is the assingment operator “=”, and on the other hand are the comparison operators “==” and “===”. You must not confuse them.
thks again for your explained reply,zdflower, by “twice” i only meant that I used the “=”-operator at two posiitions in my earlier-false code: a = += 12; this is obviously undefined. But anyway tkhs that you explained me the differrence bewtween assignment- & comparison-operator with your example! Sometimes the solution is in front of programmers’ eyes, but simply hidden in that moment.
