Comparison of 3-digit numbers

Do you remember these symbol? I've remembered!
‘=’ is the symbol of ‘equal to’
‘<’ is the symbol of ‘less than’ 18 is equal to 18 → 18 = 18
‘>’ is the symbol of ‘greater than’ 18 is less than 20 → 18 < 20
18 is greater than 15 → 18 > 15

Let’s compare the digits at ones, tens and hundreds places in these
pairs of numbers.

125 128 162 136

5 is less than 8 6 is grater than 3

So, 125 < 128 So, 162 > 136

4 is greater than 3 6 is less than 8

So, 413 > 397 So, 645 < 824

Odd and Even 3-digit Numbers
Do you remember?

Odd number of things (1, 3, 5, 7, ...) do not (1 apple)
make pairs. Odd numbers are unpaired (3 pencils)
numbers.

1, 3, 5, 7, 9, 11, ... are odd numbers.

Even number of things (2, 4, 6, 8, ...) always (2 apples)
make pairs. Even numbers are paired (4 pencils)
numbers.

2, 4, 6, 8, 10, ... are even numbers.

Now, look at the digit at ones place of 100. I got it!
It is 0 (zero). 100 is an even number.
110, 120, 130, ... 200, 250, ... are also even numbers. 300, 320, 400, 470,
etc. are even numbers.

Again, look at the digit at ones place of 101. It's easy!
It is 1 and 1 is an odd number.
So, 101 is an odd number. 201, 413, 325, 867,
949, are even numbers.
Also, the digit at ones place of 103, 105, 407, 709,
are 3, 5, 7, and 9.
3, 5, 7, and 9 are also odd numbers.
So, 103, 105, 407, 709 are odd numbers.

If the digit at ones place of a number is odd, the number is odd.
If the digit at ones place of a number is 0 or even, the number is even.
