Yes.
But, actually its an expanded LPAAO (location, person, action, adjective, object) system for 0-9 and 00-99, so 50 words/images total for the 1-digit system and 500 for the 2-digit system. For my 3-digit system it’s just one word per number, so 1000 for that. That makes 1550 total unique independent associations for numbers. All based on major system phonetics so they are pretty simple to sound out, read, and learn.
I’ve posted my complete 1 and 2 digit word lists here if interested:
At some point I may try for a 3-digit Person/Object list, which would be an additional 1000.
It may seem like a lot, but I didn’t come up with them or learn them fluently in one week. It took several months of effort before they were usable. I was realistic about my goals and expectations and took one section at a time. Now that they’ve been learned, its no problem to maintain and use them. Like I’ve said, the initial effort is worth the end result.
