Convert 124 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 >= 124

16⁰ = 1

16¹ = 16

16² = 256 <--- Stop: This is greater than 124

Since 256 is greater than 124, 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 124 is 7

Multiplying this coefficient by our original value, we get: 7 * 16 = 112

Add our new value to our running total, we get:
0 + 112 = 112

This is <= 124, so we assign our outside coefficient of 7 for this digit.

Our new sum becomes 112

Our hexadecimal notation is now equal to 7

16⁰ = 1

The highest coefficient less than 15 we can multiply this by to stay under 124 is 12

Multiplying this coefficient by our original value, we get: 12 * 1 = 12

Add our new value to our running total, we get:
112 + 12 = 124

Hexadecimal (10 - 15) are represented by an (A-F) where 12 translates to the letter C

This = 124, so we assign our outside coefficient of C for this digit.

Our new sum becomes 124

Our hexadecimal notation is now equal to 7C
