ADDC, A, NUM2HIGH ;add with carry the other high byte
MOV ANSWERHIGH, A ;save high byte answer

Answer 2

locate the 1st selection (x): - 15/x = 2 - x - 15 = - x² + 2x x² - 2x - 15 = 0 (x - 5)(x + 3) = 0 x - 5 = 0 x = 5 locate the 2d selection: x + 3 = 0 x = - 3 answer: The numbers are 5 and - 3. evidence (product is - 15) = 5 * - 3 = - 15 evidence (sum is two): = 5 - 3 = 2
