How many 4-digit even numbers?

List of answers

Lê Quốc Trần Anh Coordinator 03/07/2017 at 09:12

The least possible number is: \(1000\)

The biggest possible number is: \(9998\)

There are: \(\left(9998-1000\right):2+1=4500\left(numbers\right)\)

So there are \(4500\) 4-digit-even numbers.

The least possible number is: $1000$

The biggest possible number is: $9998$

There are: $(9998 - 1000) : 2 + 1 = 4500 (n u m b e r s)$

So there are $4500$ 4-digit-even numbers.

Thanks !
