Convert 133 from decimal to hexadecimal

(base 16) notation:

Power Test

Raise our base of 16 to a power

Start at 0 and increasing by 1 until it is >= 133

16⁰ = 1

16¹ = 16

16² = 256 <--- Stop: This is greater than 133

Since 256 is greater than 133, we use 1 power less as our starting point which equals 1

Build hexadecimal notation

Work backwards from a power of 1

We start with a total sum of 0:

16¹ = 16

The highest coefficient less than 15 we can multiply this by to stay under 133 is 8

Multiplying this coefficient by our original value, we get: 8 * 16 = 128

Add our new value to our running total, we get:
0 + 128 = 128

This is <= 133, so we assign our outside coefficient of 8 for this digit.

Our new sum becomes 128

Our hexadecimal notation is now equal to 8

16⁰ = 1

The highest coefficient less than 15 we can multiply this by to stay under 133 is 5

Multiplying this coefficient by our original value, we get: 5 * 1 = 5

Add our new value to our running total, we get:
128 + 5 = 133

This = 133, so we assign our outside coefficient of 5 for this digit.

Our new sum becomes 133

Our hexadecimal notation is now equal to 85
