How many significant figures are there in 1500?

How many significant figures is 1001?
4 sig figs
What about 1001? It has 4 sig figs. We could have “rounded” it to 1000, showing that the last digit wasn’t significant, but we didn’t. This shows that the 1 on the right is significant, and so if the smallest digit (representing 1s) is significant, then the bigger ones (representing 10s and 100s) must be also.
