Otherwise it doesn't make any sense and conveys no useful information. So when you add x3 to the end, i.e. 315x5x3, the three must modify what came before it. It would be even more confusing and illogical for it to rearrange the meaning and order of the entire sequence.
But speaking in conversation, you say "I did three sets of fahve." So writing 3x5 makes sense because you're paralleling conversational speak. The confusion is understandable, because in conversation you'd say "I did 315 for three sets of five," or "I'm crapping my pants because I have to do 315 for three sets of five tonight."
A crucial difference is that in conversation, you have the words "for" and "of" to bridge the gap. "Three sets of five" is a complete, logical, coherent thought, which you can represent numerically by writing 3x5. But in conversation, you can say, "I did 315 for three sets of five." Whereas when writing only numerically, you don't have the words "for" and "of" to explain.
So, a little confusing? Sure. But it's logically consistent both internally and as a way to express yourself when conversing vs when only writing numerically.
So 315x5x3. Or 315 for 3x5. Both work. But 315x3x5 is a nyet if you want to say 315 lbs for three sets of five reps.
Commie.
