Question

Pocket calculator had not been invented in the early seventies. What did mission control and the Apollo 13 crew use to do complicated math?

Answer 1

They used the Apollo Guidance Computer (AGC), which was a digital computer produced for the Apollo program that was installed on board each Apollo Command Module (CM) and Lunar Module (LM). The AGC provided computation and electronic interfaces for guidance, navigation, and control of the spacecraft.

Hope this helps!
