I am getting an error for entering the instructed let values in DEV tools in the console.

I entered this: let score = 5; score += 10;

let score = 20; console.log(score);

and I'm getting 2 errors for entering this. Also the console always wants to add the yellow errors to the code I enter. It looks nothing like what you're doing.

You should only declare a variable once, so try leaving off the second "let".

when you use the words 'let', 'var', 'const', you are creating a brand new variable, and a new place in memory. If you use the same variable again in the future you will not need to use these in front of the variable name since you are no longer declaring it nor creating new space, but rather using, or changing its value.
