12F₁₆

- 8C₁₆

Answer 1

Perform the following subtraction. Provide both the hexadecimal A3 and decimal 163 answer.

Explanation:
-------------
12F
=> 1x16^2+2x16^1+Fx16^0
=> 1x256+2x16+Fx1
=> 1x256+2x16+15x1
=> 256+32+15
=> 303

8C
=> 8x16^1+Cx16^0
=> 8x16+Cx1
=> 8x16+12x1
=> 128+12
=> 140

12F - 8C = 303 - 140 = 163
let's convert 163 to hexadecimal

Divide 163 successively by 16 until the quotient is 0
163/16 = 10, remainder is 3
10/16 = 0, remainder is 10
Read remainders from the bottom to top as A3
Answer: A3
