    Ummm. Could you clarify your question. The notation is very ambiguous.

    I'll try. I don't know how to type in exponents, so I just wrote in squared. [1-(-3) x 1-2]squared

    Is x a multiplication sign or variable?

    Just multiply -3 by one and you'll get this: =(1+3-2)squared =(2)squared 4

    4? Wouldn't it be 8? Because -4x4 would be 8. x is multiplication sign.

    oh, ok! so, it's the order of operations B(brackets)E(exponents)D(division)M(multiply)A(add)S(subtract)

    So, we do what's inside the inner most brackets first

    rickjbr, we need to multiply -3 and 1 before we do 1-2.

    Umm...no. I just got confused again. It turns into: [1-(-3) -2] squared. Then I get lost.

    4-2=2 2^2=4

    ok, so now, just lose the inner brackets around -3. That gets you (1--3-2)squared. and two negatives is a positive so 1--3 becomes 1+3 1+3-2 is 2. Square that and we get 4.
