Hi Philip,

The assignment is to set a default value for $context.

$base-font-size: 16px;
@function px-to-rem($target, $context: $base-font-size){

}

By writing $context: $base-font-size you are telling the compiler that if the px-to-rem() is called without the second $context argument, that it should default back to $base-font-size. Which is a variable defined as 16px. Cool huh?

It sure is cool. Thanks man, that helped me a lot.

I don't understand any of this. Sorry :/
