Not really (but then I never asked random people to multiply for me :) ). But I can kinda understand why, you almost never have to multiply 9*7 by hand. If you're doing algebra or any symbolic calculations you rarely use digits other than 0-4. In real world Benford's law + usual rounding greatly reduces the need to multiply by 7 or 9 (or 8 for that matter). |
