    This problem is killing me

    Hi I'm new and need help desperately. I have to admit I am probably not as good in math than most of the people on this site, but I tried my best and just can't figure this problem out.

    Can someone please help me out?

    1.532 x 0.659 = 0.623
    1.542 x 0.631 = 0.623
    1.589 x 0.669 = 0.554
    1.474 x 0.705 = 0.669

    I know each line is simple of course, but the actual problem is X has to match on all 4 lines....

    Any help is appreciated. Thanks in advance.

    I'm sorry, but I don't understand what you're asking...?

    Please reply with the full and exact text of the exercise and its instructions, including clarification of what "X" is supposed to indicate (is it a "times" sign, a variable, an empty slot to be filled in, or something else?) and what you mean by "X has to match" (match what? how?).

    Thank you!

    X is an empty slot to be filled. When I said X needs to match is that it has to be the same on all 4 lines.

    Here is the question:

    Please find a formula that will solve all 4:

    1.532 _ 0.659 = 0.623
    1.542 _ 0.631 = 0.623
    1.589 _ 0.669 = 0.554
    1.474 _ 0.705 = 0.669

    _ would be the blank space where the formula goes. I have no idea where to begin to create the formula.

    from the first 2 lines:
    The OPERATOR on the constants in line1
    give the same results as the OPERATOR in line2 on those constants.

    Line4 and Line5 have a constant (0.669) in common.

    That is the key to defining what the operator does.

    If ADDITION/SUBTRACTION
    subtract line2 from line1
    <br />
1.532 \,\,\square \,\, 0.659 = 0.623<br />

     <br />
1.542 \,\,\square \,\, 0.631 = 0.623<br />
    results in:
    <br />
-0.010 [ \, \square \, - \, \square \, ] +0.028 = 0<br />

    This does NOT hold if the OPERATOR is multiplication or division or exponentiation.

    Actually the formula has to be the same on all 4 lines without using the other lines to solve it.

    like this

    1_2 = 3
    2_1 = 3
    0_3 = 3
    3_0 = 3

    The answer to the above example would be + without using the other lines to solve the problem.
