In the vast world of mathematics, numbers play a crucial role in shaping our understanding of the universe. Each number has its unique characteristics, properties, and uses. In this article, we will delve into the expanded form of 47, breaking down its constituent parts and exploring its significance in various mathematical contexts.
Introduction to Expanded Form
In mathematics, the expanded form of a number is a way of expressing it as the sum of its individual digits multiplied by their corresponding place values. This representation helps us understand the structure of numbers and facilitates various arithmetic operations. The expanded form of a number can be written using the decimal system, where each digit is multiplied by a power of 10.
Expanded Form of 47
The expanded form of 47 is 40 + 7, where 4 is multiplied by 10 (the place value of the tens digit) and 7 is multiplied by 1 (the place value of the ones digit). This representation highlights the individual contributions of each digit to the overall value of the number.
Place Value System
The place value system is a fundamental concept in mathematics that allows us to represent numbers using a specific set of digits. In the decimal system, each digit in a number has a place value that corresponds to a power of 10. The place values, starting from the right, are ones, tens, hundreds, thousands, and so on.
In the case of 47, the 4 is in the tens place, and the 7 is in the ones place. Understanding the place value system is essential for performing arithmetic operations, such as addition and multiplication.
Properties of 47
47 is a unique number with several interesting properties. Here are a few:
- Prime number: 47 is a prime number, which means it can only be divided by 1 and itself. Prime numbers play a crucial role in number theory and cryptography.
