Mastering Two Digit by One Digit Multiplication: A Comprehensive Guide
Multiplication is a fundamental concept in mathematics that plays a crucial role in various aspects of life. As students progress in their mathematical journey, they encounter more complex multiplication problems, including two digit by one digit multiplication. In this guide, we will delve into the world of two digit by one digit multiplication, exploring its basics, steps, and providing a worksheet to help students practice and master this concept.
Understanding Two Digit by One Digit Multiplication
Two digit by one digit multiplication involves multiplying a two-digit number (also known as a multiplicand) by a single-digit number (also known as a multiplier). The result of this operation is a product. For example:
14 (multiplicand) × 5 (multiplier) = 70 (product)
Steps for Two Digit by One Digit Multiplication
To solve two digit by one digit multiplication problems, follow these steps:
- Write the problem: Write the two-digit number (multiplicand) and the one-digit number (multiplier) side by side, with the multiplier on the right.
- Multiply the tens digit: Multiply the tens digit of the multiplicand by the multiplier.
- Multiply the ones digit: Multiply the ones digit of the multiplicand by the multiplier.
- Add the partial products: Add the partial products from steps 2 and 3 to get the final product.
Let’s use the example from earlier to illustrate these steps:
14 × 5 =
- Write the problem: 14 × 5
- Multiply the tens digit: 10 × 5 = 50
- Multiply the ones digit: 4 × 5 = 20
- Add the partial products: 50 + 20 = 70
