    We can simplify this expression by using the difference product formula $(a-b)(a+b)=a 2-b 2$:

    789*(968-969) -788*(969-968) (splits the original expression into two smaller expressions).

    789*(969-968) -788*(969-968) (use the difference product formula for each small expression).

    Therefore, 789*968-788*969 = 1577.

    Transform 789968-788969 into (789-788)*(968+969).

    The distributive property is multiplied, i.e., a*(b+c)=ab+ac.

    Counting hail starts to rent next to (789-788) (968 + 969), 1 (1937), that is, 1937.

    The answer was 1937.
