Let's solve the multiplication problems on this worksheet. The skill being practiced is
multiplying by 100.
🔢 Rule to Remember:
When you multiply a number by
100, you add
two zeros to the end of that number.
For example:
- $ 5 \times 100 = 500 $
- $ 42 \times 100 = 4200 $
Now, let’s go through each problem:

📝 Explanation:
Multiplying by 100 shifts the digits two places to the left (or adds two zeros), which is a quick mental math trick. This helps build number sense and fluency with place value.
✔ Tip: Always check that you added exactly
two zeros — one for each zero in 100.
