While typing into the keyboard and staring at the screen of my old laptop, I attempted to multiply two integers, but when I checked the result by hand, the computer had given me the wrong answer.
The incorrect answer was exactly
13 times larger than the correct result. I repeated this process five more times with different pairs of integers and I continued to get a result exactly 13 times too large.
The products I should have obtained were:
14060592, 90675, 59906, 291375, 445208 and 67529.
Is there something wrong with my laptop?
I suspect the shift key on your laptop was broken.
The asterisk is located above the 8, so when you were trying to type (SHIFT+8) for an asterisk to indicate multiplication, you were simply putting the digit 8 in between the two integers you were trying to multiply.
This works for all but one of the products:
1827*7696 = 14060592; 14060592 * 13 = 182787696
117*775 = 90675; 90675 * 13 = 1178775
77*778 = 59906; 59906 * 13 = 778778
37*7875 = 291375; 291375 * 13 = 3787875
------
877*77 = 67529; 67529 * 13 = 877877
The 5th product you should've obtained, 445208, doesn't seem to work, though. 445208 * 13 = 5787704, but 57*7704 = 439128. So I'm not sure if this one was an error in the puzzle or if somehow my solution is incorrect/incomplete.
