In Significant figures 1 it keeps suggesting that in numbers like 292.785854000, that the trailing zeros are significant. Perhaps an associated video says something that makes that sensical. In my thoughts, if removing those zeros does not change the value, they are not significant.

Perhaps some sort of exercise preamble/description that hints at why trailing right-of-decimal zeros are significant would help?
