82 x 7 = 574
10 x 7 = 70 so 11 x 7 = 77 then 82 - 77 = 5
x2 - 83x + 82 = x2 - 82x - x + 82 = x(x-82)-1(x-82) = (x-1)*(x-82)
82 = 1 x 82, 2 x 41, 41 x 2, 82 x 1.
It is 21x - 59
7 ÷ 82 = 7/82 ≈ 0.0854.
1 x 81, 3 x 27, 9 x 9.
1 x 82, 2 x 41 = 82
738. 10 x 82 = 820, so 9 x 82 is 820 minus 82 (It is 82 less than 10 x 82)
82 x 2 = 164
32 x 82 = 2624
82 x 67 = 5494
