Describe the feature

(Extracted from #5987)
Ability to do mathematical equations (+-*/) on the crafting amount screen. For example, I need 8 upgrades for each one of 13 machines but I already have 37 upgrades stored. It would be amazing be able to just write the amount as 8 * 13-37 rather than having ALT+TAB to open a calculator discover the answer and them type 67 on the crafting amount screen.

Reasons why it should be considered

Done above.
