    Let’s try one more.
    989 × 994 =
    We use 1,000 as the reference number.
    1,000 989 × 994 =
    –11
    –6
    Subtract crossways.
    989 – 6 = 983
    or
    994 – 11 = 983
    Multiply our answer by 1,000.
    983 × 1,000 = 983,000
    Multiply the numbers in the circles.
    11 × 6 = 66
    983,000 + 66 = 983,066
    1,000 989 × 994 = 983,000
