GoMim AI | What is expanded form and How to Calculate it

Introduction

In the world of mathematics, understanding numbers in their various representations is crucial. One such representation is the expanded form, which breaks down numbers to show the value of each digit. This concept is not only fundamental in grasping the basics of arithmetic but also aids in simplifying complex mathematical problems. Dive into this article to explore the expanded form, its significance, and how you can easily calculate it.

What is it?

Expanded form is a way of expressing numbers by showing the value of each digit. It breaks down a number to show how each digit contributes to the overall number. For example, the number 345 in expanded form is expressed as 300 + 40 + 5 Here, each digit is multiplied by its place value and then summed up to represent the whole number.

Why is it important?

Expanded form is important for several reasons. Firstly, it helps students understand the concept of place value, which is foundational in mathematics. By breaking down numbers, students can see how each digit contributes to the total value, reinforcing their understanding of addition and multiplication. In real-world applications, expanded form is useful in data analysis and engineering, where precision is crucial. It also plays a significant role in exams, as it helps in simplifying problems and verifying calculations.

How to Calculate it Step-by-Step

Calculating the expanded form of a number involves breaking it down according to its place values. Here’s a step-by-step guide:

1. Identify the Place Value of Each Digit: Start from the leftmost digit and identify its place value (units, tens, hundreds, etc.).

2. Multiply Each Digit by Its Place Value: For each digit, multiply it by its corresponding place value.

3. Write the Expanded Form: Sum all the products from step 2 to express the number in expanded form.

Example:

Convert 582 into expanded form.

- The digit '5' is in the hundreds place, so its value is $$5 \times 100 = 500$$

- The digit '8' is in the tens place, so its value is $$8 \times 10 = 80$$

- The digit '2' is in the units place, so its value is $$2 \times 1 = 2$$

Thus, the expanded form of 582 is $$500 + 80 + 2$$

Related Practice Problem

Problem: Convert the number 1,473 into its expanded form.

Step-by-step Solution:

1. Identify the place value of each digit:

- '1' is in the thousands place: $$1 \times 1000 = 1000$$

- '4' is in the hundreds place: $$4 \times 100 = 400$$

- '7' is in the tens place: $$7 \times 10 = 70$$

- '3' is in the units place: $$3 \times 1 = 3$$

2. Write the expanded form by summing these values:

$$1000 + 400 + 70 + 3$$

Thus, the expanded form of 1,473 is $$1000 + 400 + 70 + 3$$
