The short of it is that anyone that can do math complicated enough for space travel has will understand binary math which is what the instructions are in.

​

The only exception would aliens that use bio organics for space travel somehow which pretty sure you wouldn't want them figuring it out from every movie and sci fi series at least.

Or space travel is so common for the aliens it would be like us and cars - everyone smart enough to use the car - but not every driver knows the engineering behind it.
