Multiplying three-digit numbers can seem intimidating at first, but with the right approach, it can be broken down into manageable steps. In this ultimate guide, we will go through the process of multiplying 85, 105, and 10 step by step.
First, we need to set up the multiplication problem:
85.
x 105.
x 10.
Next, we will multiply 85 by 105. To do this, we will multiply the ones place of 85 (5) by the ones place of 105 (5), which gives us 25. We will write down the 5 and carry over the 2 to the tens place.
Next, we will multiply the tens place of 85 (8) by the ones place of 105 (5) and add the carried over 2. This gives us 8 x 5 + 2 = 42. We will write down the 2 and carry over the 4 to the hundreds place.
Now, we will multiply the hundreds place of 85 (8) by the ones place of 105 (5) and add the carried over 4. This gives us 8 x 5 + 4 = 44. We will write down 44 as our final result for the first multiplication.
Now, we will multiply the result from the previous step (44) by 10. To do this, we simply add a zero to the right of 44, giving us 440.
Therefore, the result of multiplying 85 by 105 by 10 is 8,925. .
In summary, to multiply three-digit numbers like 85, 105, and 10, follow these steps:
1. Write down the numbers to be multiplied.
2. Multiply the ones place of the first two numbers and write down the result.
3. Carry over any tens from the previous step and add it to the product of the tens place.
4. Repeat the process for the hundreds place.
5. Multiply the result by any additional numbers if necessary.
By breaking down the multiplication process into smaller steps, you can easily tackle multiplying three-digit numbers like a pro. With practice, you will become more confident and proficient in handling such calculations efficiently.
