Convert 24 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 >= 24

8⁰ = 1

8¹ = 8

8² = 64 <--- Stop: This is greater than 24

Since 64 is greater than 24, 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 24 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 = 24, 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 24 is 1

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

Add our new value to our running total, we get:
24 + 1 = 25

This is > 24, so we assign a 0 for this digit.

Our total sum remains the same at 24

Our octal notation is now equal to 30
