Question 9588
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
