## Power Test

Raise our base of 2 to a power
Start at 0 and increasing by 1 until it is >= 32
20 = 1
21 = 2
22 = 4
23 = 8
24 = 16
25 = 32 <--- Stop: This is equal to 32

Since 32 is equal to 32, we use our current power as our starting point which equals 5

## Build binary notation

Work backwards from a power of 5

## 25 = 32

The highest coefficient less than 1 we can multiply this by to stay under 32 is 1
Multiplying this coefficient by our original value, we get: 1 * 32 = 32
Add our new value to our running total, we get:
0 + 32 = 32

This = 32, so we assign our outside coefficient of 1 for this digit.
Our new sum becomes 32
Our binary notation is now equal to 1

## 24 = 16

The highest coefficient less than 1 we can multiply this by to stay under 32 is 1
Multiplying this coefficient by our original value, we get: 1 * 16 = 16
Add our new value to our running total, we get:
32 + 16 = 48

This is > 32, so we assign a 0 for this digit.
Our total sum remains the same at 32
Our binary notation is now equal to 10

## 23 = 8

The highest coefficient less than 1 we can multiply this by to stay under 32 is 1
Multiplying this coefficient by our original value, we get: 1 * 8 = 8
Add our new value to our running total, we get:
32 + 8 = 40

This is > 32, so we assign a 0 for this digit.
Our total sum remains the same at 32
Our binary notation is now equal to 100

## 22 = 4

The highest coefficient less than 1 we can multiply this by to stay under 32 is 1
Multiplying this coefficient by our original value, we get: 1 * 4 = 4
Add our new value to our running total, we get:
32 + 4 = 36

This is > 32, so we assign a 0 for this digit.
Our total sum remains the same at 32
Our binary notation is now equal to 1000

## 21 = 2

The highest coefficient less than 1 we can multiply this by to stay under 32 is 1
Multiplying this coefficient by our original value, we get: 1 * 2 = 2
Add our new value to our running total, we get:
32 + 2 = 34

This is > 32, so we assign a 0 for this digit.
Our total sum remains the same at 32
Our binary notation is now equal to 10000

## 20 = 1

The highest coefficient less than 1 we can multiply this by to stay under 32 is 1
Multiplying this coefficient by our original value, we get: 1 * 1 = 1
Add our new value to our running total, we get:
32 + 1 = 33

This is > 32, so we assign a 0 for this digit.
Our total sum remains the same at 32
Our binary notation is now equal to 100000
