Currently, if an input into a calculated question is left blank the calculation will not run. We did not want to make any assumptions for clients that a blank answer should be treated as a 0.

However for some clients (like MRU), this is a problem. They have the inputs on the General Application, but the questions do not apply to everyone. In order to avoid blank answers, they have to make the questions required. It's an awkward (and more time consuming) experience for applicants to be required to answer questions that may not apply to them.
