Convert 14 from decimal to octal

(base 8) notation:

Power Test

Raise our base of 8 to a power

Start at 0 and increasing by 1 until it is >= 14

8⁰ = 1

8¹ = 8

8² = 64 <--- Stop: This is greater than 14

Since 64 is greater than 14, we use 1 power less as our starting point which equals 1

Build octal notation

Work backwards from a power of 1

We start with a total sum of 0:

8¹ = 8

The highest coefficient less than 7 we can multiply this by to stay under 14 is 1

Multiplying this coefficient by our original value, we get: 1 * 8 = 8

Add our new value to our running total, we get:
0 + 8 = 8

This is <= 14, so we assign our outside coefficient of 1 for this digit.

Our new sum becomes 8

Our octal notation is now equal to 1

8⁰ = 1

The highest coefficient less than 7 we can multiply this by to stay under 14 is 6

Multiplying this coefficient by our original value, we get: 6 * 1 = 6

Add our new value to our running total, we get:
8 + 6 = 14

This = 14, so we assign our outside coefficient of 6 for this digit.

Our new sum becomes 14

Our octal notation is now equal to 16
