(-9 x 4) - (8 - -3) x 2

Through workings I got -94 (Smirk)

So that's, because of BODMAS;
$-36 - 2(11) = -36 - 22 = -58$

Can you explain that a little further?

what is BODMAS?

It's the order of calculations.
Brackets
Other (alternatively Indices)
Division
Multiplication
Addition
Subtraction

So, in your calculation, you'd do the brackets first, giving;

$-36 - 11 * 2$

From there, BODMAS applies, meaning you do the multiplication first, giving;

$-36 - 22 = -58$

Hope that made things a bit clearer.

(-36)-(11)(2)
-36-22
= -58 (Wondering)

Not being rude here, just logical: If you show me yours, I'll show you mine. If you want us to verify your answer, would a simple "yes" or "no" be enough of an answer for you? I'm personally OK with that, if that's really what you want. But if you want someone to type out a full solution, would you not best do the same as a matter of courtesy.

As you see, "No" would have been appropriate here.
