๐ Understanding Place Value: Ones vs. Tens
In math, understanding place value is crucial. It tells us the value of a digit based on its position in a number. Let's focus on the ones and tens places.
๐ข Definition of the Ones Place
The ones place is the rightmost digit in a whole number. It represents how many individual units there are.
- ๐ Example: In the number 7, the 7 is in the ones place, meaning there are 7 ones.
- โ Value: The value of a digit in the ones place is simply the digit itself.
- ๐งฎ Range: The digits in the ones place can be 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9.
๐ฏ Definition of the Tens Place
The tens place is the digit to the left of the ones place. It represents how many groups of ten there are.
- ๐๏ธ Example: In the number 30, the 3 is in the tens place, meaning there are 3 tens, or 30.
- โ๏ธ Value: The value of a digit in the tens place is the digit multiplied by 10. For example, if the digit is 4, its value is $4 \times 10 = 40$.
- ๐ Range: The digits in the tens place can also be 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9.
