Simple Example
Quick Example
Imagine you have 100 cricket balls, and then your friend gives you 5 more. Now you have a total of one hundred five (105) cricket balls. It's like having one full century plus five extra runs in a match!
Worked Example
Step-by-Step
Let's find out how many items make up one hundred five. --- Step 1: Start with the number 100. This is like having 10 bundles of 10 items each. --- Step 2: Now, we need to add 'five' more to this. --- Step 3: Count 1, 2, 3, 4, 5. --- Step 4: Add these 5 items to your 100 items. --- Step 5: 100 + 5 = 105. So, one hundred five means exactly 105 items.
Why It Matters
Understanding numbers like 105 is crucial for everyday life and future studies. It helps in counting money, tracking scores in games, or even managing inventory in a shop. Doctors use numbers to count pulses, and engineers use them to measure distances.
Common Mistakes
MISTAKE: Writing '1005' when someone says 'one hundred five'. | CORRECTION: 'One hundred five' is written as '105'. '1005' is 'one thousand five'.
MISTAKE: Confusing the order, thinking 105 comes before 100. | CORRECTION: Numbers increase as you count. 100 comes first, then 101, 102, 103, 104, and finally 105.
MISTAKE: Forgetting the 'zero' in the middle and writing '15'. | CORRECTION: 'One hundred five' means one hundred, zero tens, and five ones. So the '0' is important: 105.
