 Question 162646: Hi, I have a problem in which the first part of the equation is 6[8-(Y+4)]. I have the solution to this problem, and I understand all the operations except, the first step which is to remove the parentheses around Y+4 and to change the sign here to Y-4. Then, this part of the equation becomes 6(8-Y-4). What rule is being applied here that allows me to change the order of operations by removing the parentheses and changing the sign from + to - ?
