Convert 26 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 >= 26

8⁰ = 1

8¹ = 8

8² = 64 <--- Stop: This is greater than 26

Since 64 is greater than 26, 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 26 is 3

Multiplying this coefficient by our original value, we get: 3 * 8 = 24

Add our new value to our running total, we get:
0 + 24 = 24

This is <= 26, so we assign our outside coefficient of 3 for this digit.

Our new sum becomes 24

Our octal notation is now equal to 3

8⁰ = 1

The highest coefficient less than 7 we can multiply this by to stay under 26 is 2

Multiplying this coefficient by our original value, we get: 2 * 1 = 2

Add our new value to our running total, we get:
24 + 2 = 26

This = 26, so we assign our outside coefficient of 2 for this digit.

Our new sum becomes 26

Our octal notation is now equal to 32
