We are going to focus on three:
Standard
Written
Base-10
Here is an example of a written number using each method:
---------------------------
Standard form is just how it sounds. Standard. This is how we usually write numbers when solving math problems. Pretty standard stuff.
We can also write a number out in words. When doing this, it helps to say the number aloud. Then write what you hear. If there is a decimal, you write "and." That's the only time "and" should be in the written form of the number.
This video will help explain how to read a number that includes a decimal.
Base-10 numbers are written as products added together. Use place values to help you. Imagine collecting base-ten blocks to show the value of the number. Essentially, that's how this form breaks down.
Here's a comparison:
Now you're getting the hang of it.
