• Making it easier to perform arithmetic operations, such as addition and subtraction
• Allowing for a deeper understanding of numbers and their relationships
• Enhancing problem-solving skills

Expressing 45.803 in Expanded Form

To express 45.803 in expanded form, we need to break it down into its individual digits and their respective place values. The number 45.803 can be expressed as:

4 × 10^1 + 5 × 10^0 + 8 × 10^-1 + 0 × 10^-2 + 3 × 10^-3

Simplifying this expression, we get:

40 + 5 + 0.8 + 0.03

Therefore, the expanded form of 45.803 is:

40 + 5 + 0.8 + 0.03

Step-by-Step Guide to Expressing Numbers in Expanded Form

Expressing numbers in expanded form is a straightforward process. Here's a step-by-step guide:

1. Write the number you want to express in expanded form.
2. Identify the place value of each digit.
3. Multiply each digit by its respective place value.
4. Write the results as a sum of the individual digits multiplied by their place values.

Example: Expressing 234.56 in Expanded Form

Using the steps outlined above, we can express 234.56 in expanded form as:

2 × 10^2 + 3 × 10^1 + 4 × 10^0 + 5 × 10^-1 + 6 × 10^-2

Simplifying this expression, we get:

200 + 30 + 4 + 0.5 + 0.06

Therefore, the expanded form of 234.56 is:

200 + 30 + 4 + 0.5 + 0.06
