How to avoid overflow in expr. A * B - C * D
...c * d
x / (a * d) = (a * b - c * d) / (a * d)
x / (a * d) = b / d - c / a
now, the integer/mod stuff:
x / (a * d) = (b / d + ( b % d ) / d) - (c / a + ( c % a ) / a )
x / (a * d) = (b / d - c / a) - ( ( c % a ) / a - ( b % d ) / d)
x = (b / d - c / a) * a * d - ( ( c % a ) * d - ( b % d ) * a)
