What resistor should be paralleled to a 100 ohm resistor so that the equivalent resistance is 32 ohm?

On the WP34S I just do

100 +/- [ENTER] 32 [g] || => 47.0588235294

Indeed,

100 [ENTER] 47 [g] || => 31.9727891156

Is there another calculator that offers this as a built-in function?

Is that really any easier than 32 1/X 100 1/X - 1/X ?
