How we worked it out

Updated as you change the numbers.

  1. Each hex digit is worth 16 times the digit to its right. The numbers are converted to exact integers, combined, and converted back.

Method and assumptions

In base 16, the digits from the right are worth 1, 16, 256, … To convert a decimal number, divide by 16 repeatedly and read the remainders from last to first. Negative results are shown with a minus sign rather than in two’s complement.
