Easy Guide: Writing Numbers in Expanded Form with Decimals

Writing Numbers in Expanded Form (with Decimals)

When you write a number in expanded form (also known as expanded notation), you are expressing the number separated into its composite individual place values (and decimal values if necessary) in the form of an expression.

An easy way of thinking about writing numbers in expanded form is taking apart a number into its specific place values. The place value chart below is a good review of the value of each number slot.

Conversely, writing a number in standard form (or numeric form) is the opposite or reverse of writing a number in expanded form.

Click here to download this chart as an easy-to-print PDF file.

Writing a Number in Expanded Form Example

Example: Write 8,743 in expanded form

8,743 = 8,000 + 700 + 40 + 3

Note how the use of a place value chart can help you write numbers in expanded form.

Writing a Number in Expanded Form with Decimals Example

Example: Write 317.29 in expanded form.

317.29 = 300 + 10 + 7 + 0.2 + 0.09

This strategy applies to all problems that require you to read or write numbers in expanded form.

Check out the free video lesson below to learn more about how to write numbers in standard form with decimals and without.

Reflection Over The X and Y Axis: The Complete Guide

What is a Reflection in Math?

Learning how to perform a reflection of a point, a line, or a figure across the x axis or across the y axis is an important skill that every geometry math student must learn.

In real life, we think of a reflection as a mirror image, like when we look at own reflection in the mirror.

This idea of reflection correlating with a mirror image is similar in math.

This complete guide to reflecting over the x axis and reflecting over the y axis will provide a step-by-step tutorial on how to perform these translations.

 First, let’s start with a reflection geometry definition:

Math Definition: Reflection Over the X Axis

A reflection of a point, a line, or a figure in the X axis involved reflecting the image over the x axis to create a mirror image. In this case, the x axis would be called the axis of reflection.

Math Definition: Reflection Over the Y Axis

A reflection of a point, a line, or a figure in the Y axis involved reflecting the image over the Y axis to create a mirror image. In this case, the Y axis would be called the axis of reflection.

What is the rule for a reflection across the X axis?

The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same.

For example, when point P with coordinates (5,4) is reflecting across the X axis and mapped onto point P’, the coordinates of P’ are (5,-4). Notice that the x-coordinate for both points did not change, but the value of the y-coordinate changed from 4 to -4.

What is the rule for a reflection across the Y axis?

The rule for reflecting over the Y axis is to negate the value of the x-coordinate of each point, but leave the -value the same.

For example, when point P with coordinates (5,4) is reflecting across the Y axis and mapped onto point P’, the coordinates of P’ are (-5,4). Notice that the y-coordinate for both points did not change, but the value of the x-coordinate changed from 5 to -5.

You can think of reflections as a flip over a designated line of reflection. You can often visualize what a reflection over the x axis or a reflection over the y axis may look like before you ever apply any rules of plot any points. This aspect of reflections is helpful because you can often tell if your transformation is correct based on how it looks. If the new image resembles a mirror image of the original, you’re in good shape! If it does not, you probably did something wrong.

Examples of Reflection Over the X Axis and Y Axis:

Notice how the reflection rules for reflecting across the x axis and across the y axis are applied in each example.
