You can put this solution on YOUR website! Ok, for these types of problems, you need to use the Order of Operations (Parenthesis, Exponents, Mulitply, Divide, Add, and Subtract) - commonly known as PEMDAS.
So, the first thing you would do would be to solve for (2-5). ----> 2-5 = -3
Then, take 9-6, which is next in line in solving the parenthesis (you always do what's in the actual parenthesis first, then what's in the brackets next). ----> 9-6 = 3
Take the two answers and multiply them together. ----> [9-6(2-5)] = [3(-3)] = -9
Next in the Order of Operations for this expression is Addition. ----> 3+4 = 7
And you take 7 and -9 and multiply them together and you have your answer.
Therefore:
3+4[9-6(2-5)]
3+4[9-6(-3)]
3+4[3(-3)]
3+4(-9)
7(-9)
= -63
