Convert 115 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 >= 115

16⁰ = 1

16¹ = 16

16² = 256 <--- Stop: This is greater than 115

Since 256 is greater than 115, 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 115 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 <= 115, 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 115 is 3

Multiplying this coefficient by our original value, we get: 3 * 1 = 3

Add our new value to our running total, we get:
112 + 3 = 115

This = 115, so we assign our outside coefficient of 3 for this digit.

Our new sum becomes 115

Our hexadecimal notation is now equal to 73
