Why can't everything be in standard form (not that I don't like expanded form)?

you have to learn the differentskills for life

why do we have to practice

It isn't practical to write out large numbers in words most of the time. It's more of understanding how all numbers can be written as their digits multiplied by their respective power of 10. If you ever write a check though, you will need to write the amount of money in words.

what are energy points for?

not only that its also to get badges and to make u feel nice :]

Whole numbers in written form review

Google Classroom

Review writing whole numbers in written form, and try some practice problems.

Written form

Written form is a way to write numbers using only words.

Example

Let's write

7, 229

in expanded form.

Thousands	Hundreds	Tens	Ones
$7$ ‍	$2$ ‍	$2$ ‍	$9$ ‍

7229 = 7 thousands

+ 2 hundreds +

2 tens + 9 ones

= 7000 + 200 + 20 + 9

7229

in written form is

seven thousand, two hundred twenty- nine
