What is 10 of 15?
Multiplication is an essential arithmetic operation; using this multiplication, we can combine quantities, determine the total of repeated additions, and calculate the product of two or more numbers. In this article, we will learn about the product of 10 and 15 in a detailed manner by breaking down the process, examining different methods, and exploring realworld examples; after that, we will understand how these numbers interact and how their product is determined.
Understanding Multiplication
Multiplication is a process that combines two or more numbers to obtain a result which we call a product. The symbol is "*," and "x" represents the multiplication. Multiplication is usually defined as a shortcut to repeated additions; for example, consider the multiplication of 2 and 4, i.e., 8, and we can also write this as adding 4 two times or adding 2 four times; both are identical, i.e., 4 + 4 = 8 or 2 + 2 + 2 + 2 = 8.
Multiplying 10 and 15
We multiply the two numbers to determine the product of 10 and 15. Let's explore the methods to calculate the product:
 Method 1: The Traditional multiplication: This traditional method requires multiplying each value and adding the resulting products; using this traditional method, we get the product of 10, and 15 is 150.
 Method 2: Expanded Multiplication: Another method to calculate the product is by expanding the numbers into their place value form.
10 × 15 = 10 x (10 + 5) = (10 x 10) + (10 x 5) = 100 +50 = 150
Using this, we get the product of 10, and 15 is 150.
 Method 3: Mental Calculation: For smaller numbers like 10 and 15, mental calculation can be a quick and efficient method. This can be done by recognizing patterns and applying basic arithmetic operations, we can find the product without relying on written methods. In this case, we know that multiplying any number by 10 involves adding a zero at the end. Therefore, multiplying 15 by 10 would result in 150. Using this method, we get the same number as the product, 150.
RealWorld Applications
Understanding multiplication and the product of numbers has many practical applications in everyday life. Let's explore some realworld scenarios where the product of 10 and 15 is relevant.
 Unit Conversion: If we convert 10 meters into centimeters, we need to know that 1 meter equals 100 centimeters. By multiplying 10 meters by 100 centimeters per meter, you find that 10 meters is equivalent to 1000 centimeters.
 Area Calculation: Suppose we have a rectangular garden with a length of 10 meters and a width of 15 meters. To find the area of the garden, we multiply the length by the width; in this case, the area of that rectangle would be 10 meters × 15 meters, which equals 150 square meters.
 Cost Calculation: Imagine we want to buy 10 books, each costing $15. By multiplying the number of books (10) by the price per book ($15), we can calculate the total cost of the books; in this case, the total cost would be $150.
 Time and Speed: Suppose we are traveling at a speed of 10 kilometers per hour, and you need to cover a distance of 150 kilometers. We can calculate the total distance covered by multiplying the speed (10 kilometers per hour) by the time taken (15 hours). In this example, the distance covered would be 10 kilometers per hour × 15 hours, resulting in 150 kilometers.
Conclusion
Multiplication is an essential mathematical operation that can allow us to combine quantities, determine repeated addition, and find the product of the numbers. In our case, the multiplication of 10 and 15, the product is 150. Understanding this concept can help us solve reallife problems like unit conversion, calculating cost prizes, and calculating areas and distances. After getting knowledge of this powerful mathematical tool, we have gained the power to solve practical problems.
