🔢 Detailed Explanation of Multiply by 10

When you multiply any number by 10, something special happens to the number. It gets bigger, and the digits move to the left. This means the place value of each digit changes!

❓ What Does Multiply by 10 Mean?

Multiply means to add a number to itself a certain number of times. When we multiply by 10, we are adding the number to itself 10 times. But there is a quicker way to do this.

➡️ How Does Multiplying by 10 Change a Number?

When you multiply a number by 10, the digit moves one place to the left on the place value chart. For example, if you have the number 4, it is in the ones place, but when you multiply by 10, it moves to the tens place, making it 40.

🏷️ Use of Place Value

Let’s look at the number 23. The 2 is in the tens place, and the 3 is in the ones place. When you multiply 23 by 10:

  • The 2 moves from the tens place to the hundreds place.
  • The 3 moves from the ones place to the tens place.
  • You get 230.

🔍 Recognising Patterns

A quick way to see this pattern is by adding a zero to the end of the number. For example:

  • 5 × 10 = 50
  • 12 × 10 = 120
  • 7 × 10 = 70

Every time, the number gets bigger by ten times, and you just add a zero at the end.

🎯 Examples

  • 3 × 10 = 30
  • 15 × 10 = 150
  • 9 × 10 = 90

💡 Tips

  • Remember the digits move one place to the left when you multiply by 10.
  • You can think of it as adding a zero at the end of the number.
  • Use your place value chart: ones to tens, tens to hundreds, and so on.
  • Practice with different numbers to see the pattern clearly.

Multiplying by 10 is easy once you know that the digits just shift places and the number grows ten times bigger!
