    there is no clue…
    split into 3 part 3*1 matrix.
    then hit and trial for S={0-9}
    case 1:
    S=0,then U=even,M=5;
    case 2:
    s=1, U,M={3,7 or 7,3}
    s=2, U,M={3,4},{4,3}………..{8,9},{9,8}
    it will satisfy at S=2, and U=3,M=4……
    7 4 3
    6 7 4
    ……………………….
    2 9 7 2
    5 2 0 1
    4 4 5 8
    ………………………
    5 0 0 7 8 2

    m+1=x
    if m=4
    then
    m+1=x=5 put the value then observe and find best option

    z*z=x_
    means
    7*7=49
    put z=7
    m=4
    E=6 e*z=mm 6*7=42
    u=3

    7 4 3
    6 7 4
    ……………………….
    2 9 7 2
    5 2 0 1
    4 4 5 8
