Question

subtract the face value of the digit at the thousands place from its place value.

Answer 1

Hi!

We should remember that every digit should be or be less than 9.
Also that, there are only 5 odd one digit numbers.

So the number can be anything like -
13579
13597
15397 , etc.

So let's jump to algebra. Can we?

So let the number be 'abcde'
Here they are not being multiplied but they are the digits, ok?

So the thousands digit is 'b'
What's the face value of b? It's b
And the place value? Of course 1000b
Let's subtract them now. So it becomes

1000b - b
= 999b

There's your answer!

Hope you found my answer useful .
