    wait a minute...
    7-3 first number is 7+3=10
    6+3 first number is 6-3=3
    5-2 first number is 5+2=7
    11+2 first number is 11-2=9
    so 15-3 first number is 15+3=18

    7-3 2nd number (7-3)*3 = 12
    6+3 2nd number (6+3)*3 = 27
    5-2 2nd number (5-2)*2 = 6
    11+2 2nd number (11+2)*2=26
    so 15-3 2nd number is (15-3)*3= 36

    7-3 final number is 7-3=4
    6+3 final number is 6+3=9
    5-2 final number is 5-2=3
    11+2 final number is 11+2=13
    so 15-3 final number is 15-3=12

    Not that difficult if you look at it for a few minutes

    It's 183612. First I figured out the last digit has to be 15-3, the first digits are 15 + 3 and the middle digits are 3*12 multiplied. after figuring out the first pattern, the others fell into place

    15-3=12
    15+3=18
    12*3=36
    therefore ans = 183612

    The sum equals the last number(s), the difference equals the first number(s), and the product of the sum and the second number in the operation is the middle number.
    15-3=12
    15+3=18
    (15-3)(3)=36
