Worked Example

Step-by-Step

---
2. **Understand place value:** Each digit has a 'place' or position.
---
3. **Ones place:** The digit '3' is in the ones place. This means it represents 3 x 1 = 3.
---
4. **Tens place:** The digit '0' is in the tens place. This means it represents 0 x 10 = 0.

Common Mistakes

MISTAKE: Reading 103 as 'one hundred and three-zero'. | CORRECTION: The '0' in the tens place means 'zero tens', so we simply read it as 'one hundred three' or 'one hundred and three'.

MISTAKE: Confusing 103 with 130 or 1003. | CORRECTION: Pay close attention to the order and position of the digits. 103 has three digits, with 0 in the tens place. 130 has 3 in the tens place. 1003 has four digits.

MISTAKE: Thinking 103 is an even number. | CORRECTION: A number is even if it ends in 0, 2, 4, 6, or 8. Since 103 ends in 3, it is an odd number.
