Describe your issue in detail here.

Your code so far

Convert the assignments for a , b , and c to use the += operator.
Please this was what i was asked to do but i don’t know why i wasn’t able to pass this level.
Please someone should help me out.

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

// Only change code below this line
a += 12;
9 += b;
c += 7;

This looks different from the other two. Spell it out, what this means is:

9 = 9 + b;

Can the number 9 really also be equal to the number 9 plus some other number stored in b (other than 0)? That’s like saying that 10 is equal to 20.

This was the instruction below.
Convert the assignments for a , b , and c to use the += operator.
But i did exactly what i was asked to do but i don’t know why i wasn’t able to pass and it was saying i should use the =+ signs in each variable when i already did.
Your code so far

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

// Only change code below this line
a = a += 12;
b = 9 += b;
c = c += 7;

So given the += operator, what do you think it is actually doing? If we have

let a = 5;

// and later...
a += 12;

In that case, what does the “plus equals” mean?

7

Sorry i did changed my answer to
a += 12;

9 += b;

c += 7;
but i didn’t pass. Can you help me out.

What is the difference between

9 += b;

and

b += 9;

The left side is always what we are assigning a value to. The right side is the value we are assigning.

Can we assign a value to 9?

Thank you so much, I didn’t knew it was 9 +=b; was where i was wrong.
