Hey there, math explorers! Ever feel a little intimidated by bigger multiplication problems? Don’t worry, we’ve all been there. But guess what? Breaking down those problems can make them a whole lot easier and even dare I say fun!
Today, we’re going to conquer the challenge of multiplying a two-digit number by a three-digit number. It might sound complicated, but trust me, with a little practice and the right approach, you’ll be a multiplication master in no time! So, let’s dive in!
Unlocking the Secrets of 2 by 3 Digit Multiplication
Let’s start with an example: 25 x 123. The trick is to break it down. Think of 25 as (20 + 5). Now, we’re going to multiply 123 by both 20 and 5 separately. This is like solving two smaller, easier problems!
First, let’s multiply 123 by 5. This is pretty straightforward! You should get 615. Write that down it’s our first partial product. It’s important to keep things organized, especially when we are dealing with bigger numbers.
Next, we multiply 123 by 20. Remember that 20 is just 2 x 10. So, we can multiply 123 by 2, which gives us 246, and then multiply that by 10 (just add a zero!), resulting in 2460. This is our second partial product.
Now, the final step: Add the two partial products we calculated! That means adding 615 and 2460. When you add them together, you get 3075. That means 25 multiplied by 123 is equal to 3075. Congratulations, you did it!
