Convert 7 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 >= 7

16⁰ = 1

16¹ = 16 <--- Stop: This is greater than 7

Since 16 is greater than 7, we use 1 power less as our starting point which equals 0

Build hexadecimal notation

Work backwards from a power of 0

We start with a total sum of 0:

16⁰ = 1

The highest coefficient less than 15 we can multiply this by to stay under 7 is 7

Multiplying this coefficient by our original value, we get: 7 * 1 = 7

Add our new value to our running total, we get:
0 + 7 = 7

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

Our new sum becomes 7

Our hexadecimal notation is now equal to 7
