Short Answer

Expert verified

Step by step solution

- Understand the Problem

The exercise asks to multiply two given numbers, which are 28 and 1. Multiplication is one of the basic arithmetic operations.

- Apply the Multiplication Rule

Recall that multiplying any number by 1 results in the number itself. This is known as the identity property of multiplication.

- Perform the Multiplication

Using the identity property of multiplication, multiply 28 by 1: $28 \times 1 = 28$.

- Write the Final Answer

The product of 28 and 1 is 28.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

arithmetic operations

Before diving into solving multiplication problems, it's essential to understand arithmetic operations. These include addition, subtraction, multiplication, and division. They are the foundation of all mathematical calculations. Multiplication, one of these core operations, involves combining groups of the same size. For example, if you have 3 groups of 2 apples, multiplying 3 by 2 gives you the total number of apples: 6. Understanding these basic operations helps in solving various mathematical problems efficiently.

identity property of multiplication

The identity property of multiplication is a fundamental concept in math. It states that any number multiplied by 1 will result in that number itself. This means if you multiply 5 by 1, you get 5. If you multiply 100 by 1, you get 100. This property simplifies calculations and helps to verify the correctness of other operations. For example, in the exercise, multiplying 28 by 1 results in 28. This property is handy because it doesn't change the value of the original number and makes solving problems straightforward.

basic multiplication

Basic multiplication involves repeated addition. For instance, multiplying 4 by 3 is the same as adding 4 three times: 4 + 4 + 4 = 12. It's a quick way to calculate large sums. When you're comfortable with your multiplication tables, solving problems becomes faster and easier. In the given exercise, you use basic multiplication along with the identity property to find that 28 multiplied by 1 is 28. These principles help in tackling more advanced math topics and real-life scenarios, like calculating the total cost of multiple items.
