$$A = 743000$$ and $$B = 800100$$. Which is greater $$A$$ or $$B$$? And by how much?
Given
$$A = 743000$$
$$B = 800100$$
$$B$$ is greater than $$A$$ i.e. ($$B > A$$)
Since both the numbers have $$6-digits$$ numbers
At the leftmost, the first number has $$7$$ and the second number has $$8$$
We know that,
$$8 > 7$$
Hence, $$800100 > 743000$$ i.e $$B > A$$
$$B$$ is greater than $$A$$ by = $$800100 – 743000$$
$$= 57100$$
