Your code so far

let b = 9;
let c = 3;
// Only change code below this line
a -= 6;
b -= -15;
c -= 2;

Challenge: Basic JavaScript - Compound Assignment With Augmented Subtraction
Link to the challenge:
Look carefully at the example given in the exercise’s description: you need to use it as a model. Also, there’s something that’s not supposed to be there in your code.

not getting it
a -= 6;
b -= -15;
c -= 7;```
We can come up with some generic example
If I say
stuff = stuff - anotherStuff
it’s the same as
stuff -= anotherStuff

helps. got a and b. stuck on c for some reason.
a -= 6;
b -= 15;
c -= -3;
you have originally
c = c - 1;
so why are you using -3
here?

honestly IDK. I was trying to get it right. Math is not my strong suit. I am an artist by experience (and DNA :-))

This is a negative number: -3

don’t think I am dumb yet I don’t get the importance of being a negative number
This step is not about math or negative/positive numbers actually.
Here they are just showing you some syntax, how things can be written in JavaScript
Try not think about math.
Think about this stuff as about abbreviations
I can write in the code:
a = a + 100;
it will work
but I can be a little bit more consice:
a += 100
