How do you do checks for checkboxes?

Checkboxes may have multiple combinations.

Why is your conditionals only having EQUAL or NOT EQUAL and nothing for something like in_array?

e.g.

field: choices [a, b, c, d]

field: a_qty

field: b_qty

field: c_qty

field: d_qty

I want a_qty to be visible only when a is selected in field: choices

I want a_qty to have value 0 when it's not selected

It's lame that using Show/Hide a_qty is visible when you do: choices = a

But then when I do https://www.screencast.com/t/cEHkvWqB

suddenly, the not equal operator is checking not if the item is chosen but account for the other options being chosen or not

Can I do calculation when a field get's hidden?

I checked your form (https://www.jotform.com/72593234693464) and it seems you have set the default value of the fields into 0.

Can I do the calculation when a field get's hidden?

Yes, you can still do calculation even the field is being hidden. Just make sure that you have set the Clear Hidden Field Values to Don't clear so that the values will not be clear if it hidden.
