Which digit represents the units in the number 10?

Step-by-step solution

To solve this problem, it is crucial to apply an understanding of the place value system in decimal numbers. The decimal (base 10) number system presents digits from right to left in increasing powers of 10.

Let's analyze the number 10. This number comprises two digits: '1' and '0'. In the decimal system, the rightmost digit is termed the units digit. Thus, for the number 10, the digit '0' resides in the units place.

Therefore, the digit representing the units place in the number 10 is 0 0 .

Key Points to Remember

Essential concepts to master this topic
  • Rule: The rightmost digit always represents the units place
  • Technique: In 10, read right to left: 0 is units, 1 is tens
  • Check: Count positions from right: first position is units place ✓

Common Mistakes

Avoid these frequent errors
  • Thinking the first digit is always the units digit
    Don't assume the leftmost digit '1' in 10 is the units digit = wrong answer! This confuses reading order with place value position. Always count positions from right to left to find the units place.

FAQ

Everything you need to know about this question

Why isn't the '1' in 10 the units digit if it comes first?

+

In place value, we read positions from right to left, not left to right like regular reading. The '1' in 10 is actually in the tens place because it's the second digit from the right.

What does it mean that 0 is in the units place?

+

Having 0 in the units place means there are zero individual units. The number 10 has 1 group of ten and 0 individual units, which equals 10 total.

How do I remember which digit is in the units place?

+

Always start counting from the rightmost digit! The first position on the right is units, second is tens, third is hundreds, and so on.

Is the units place the same as the ones place?

+

Yes! Units place and ones place mean exactly the same thing. Both terms refer to the rightmost digit position in any whole number.

What if a number has only one digit, like 7?

+

Single-digit numbers are always in the units place! So in the number 7, the digit 7 represents the units.
