There are only ten digits in all math:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9
When counting, what comes after 9? š¤
Yes, it's 10! šĀ
We add a second digit.
But why is it 10 and not 01? š¤
Because each place in a number has a different value.
Ā Ā Ā Ā Ā The rightmost (š) digit is called the Ones place digit.
Ā Ā Ā Ā Ā The Tens place is always left (š) of the Ones place.
Ā Ā Ā Ā Ā Digits on the left (š) are always worth more.
23 has 2 Tens and 3 Ones.
Let's look at the number 37.
Which digit is in the Tens place?
3
How much is that digit worth?
Ā Ā Ā Ā Ā Each Ten is worth to 10 Ones.
So 3 Tens equals 30 Ones. ā
Ā Ā Ā Ā Ā To make numbers greater than 9, we use multiple digits.
Ā Ā Ā Ā Ā Each digit has a different value, depending on where it is in the number. That's why 21 is greater than 12, for example.
Ā Ā Ā Ā Ā The rightmost (š) digit has the smallest value. It's called the Ones place digit.
Great job! šŗ
