Question 209380: Theme: 2 Sets of Parenthesis Nested within Each Other
My question: Why does answer, "36" move from (-36) when removed from parenthesis as the last operation of this solution? I need simple but rule based reference of where to study up on how to manipulate parentheses within mathematical/algebraic rules. Thank you.
My solution follows:
(9 + 3 - 4 * ( 8 + ( - 2 ) ^2) )
----
Step 1: Find 1st set of inner parenthesis ( - 2 ); No operation indicated;
Step 2: Proceed to next set of inner parenthesis: ( 8 + ( - 2 ) ^ 2 ). Process. 2 ^ 2 = 4;
( 8 + ( 4) ) = ( 12 ). Rewrite equation: ( 9 + 3 - 4 * (12) )
Step 3: All parenthesis and powers are resolved. Now proceed to Multiply, Divide; then Add, Subtract.
So, 4 * 12 = 48; Rewrite: ( 9 + 3 - 48 ). Solve: ( 12 - 48 ) = ( -36 ). Remove parenthesis: A: 36

Question 215105: 5x-7(x-6). The answer in the back of the book says -2x+42 but I can't figure out how they arrived at that! Please help!!! I understand the concept of FOIL (First, Outside, Inside, Last) but for some reason I can't seem to get beyond 5x squared. 5x squared - 30x -7x +42, then what? Like terms? Or do I divide by "x"? EEEK!
