subtraCtion of numbers

In the previous class, we have learnt subtraction of numbers up to 9999. Here we
will extend our learning and subtract bigger numbers, that is, 5 and 6-digit numbers.

Let us continue the conversation between Madhu and Megha.
Madhu: Also tell me, how many more fauna species are there than flora species?

Megha: As I told you earlier, there are over 81,000 species of fauna and 47,000
species of flora have been found. So, around 34,000 more species of fauna are there

than flora in our country.
Madhu: How do you calculate their difference so easily?

Megha: With the help of subtraction.
81,000 – 47,000 = 34,000. This is a subtraction of 5-digit numbers.
