Comparing bigger numbers
Chandu and Sindhu are making numbers with digits 0-9 again
Comparing bigger numbers (Big Numbers - 5th Class)
Chandu : How do you know that your number is bigger than mine?
Sindhu : Let me show you.

She writes in her notebook.

3671 = 3 thousands + 6 hundreds + 7 tens + 1 one
= 3000 + 600 + 70 + 1

3167 = 3 thousands + 1 hundred + 6 tens + 7 ones
= 3000 + 100 + 60 + 7

There are 3 thousands in both 3671 and 3167. However, there are 6 hundreds in
3671 and 1 hundred in 3167.
So, 3671 is more than 3167.

Now, you make all the four digit numbers that are possible with the digits 3, 6, 7, 1.
Hint : 24 such numbers are possible
