I'm still not understanding. I don't know what code to put where and i'm just guessing.. const num1 = prompt("Please input a number"); num1 = parseFloat(num1);

I get uncaught type error Assignment to constant variable?

But if i change const to let it runs without errors is that because a const cannot be changed?

Constants are block-scoped, much like variables defined using the let keyword. The value of a constant can't be changed through reassignment, and it can't be redeclared. source = https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/const

that being said, unless you trying to run an unchangeable variable use 'let' instead of 'const'.
