Write the largest number of $$6$$ digits and the smallest number of $$7$$ digits. Which one of these two is larger and by how much?
The largest $$6$$ digit number $$=9,99,999$$
The smallest $$7$$ digit number $$=10,00,000$$
Clearly, $$10,00,000$$ is the larger than $$9,99,999$$
And their difference$$=10,00,000-9,99,999=1$$
Hence $$10,00,000$$ is the larger than $$9,99,999$$ by $$1$$.
