First time using JavaScript

Hello, I'm making a Calculator using HTML and JavaScript got the HTML UI part looking good, but need help with the JavaScript guts In short I have a number of inputs, 1-however many, and want to be able to take those inputs and shove them through 2 known Formulas, then sort the outputs by how many inputs are included in the output e.g. 3 inputs should make the outputs of 1, 2, 3, 1+2, 1+3, 2+3, 1+2+3 there are other things I want to do but those are for later
