Question: `q001YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY
Your solution:
The order of operations requires that you must do what is in parenthesis first, then exponents, multiplication, division, addition, and subtraction in the order they appear making the solutions of the problems different even though they contain the same numbers.
X - 2 / x + 4 (x - 2) / (x + 4)
2 - 2 / 2 + 4 (2 - 2) / (2 + 4)
2 - 1 + 4 0 / 6
1 + 4 = 5 = 0

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY
Your solution:
The order of operations requires that you must do what is in parenthesis first, then exponents, multiplication, division, addition, and subtraction in the order they appear making the solutions of the problems different even though they contain the same numbers.
2 ^ x + 4 2 ^ (x + 4)
2 ^ 2 + 4 2 ^ (2 + 4)
4 + 4 = 8 2 ^ 6 = 64

Question: `q003
YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY
Your solution:
The numerator is: 3
The denominator is: [ (2x - 5) * 3x + 1]
X - 3 / [ (2x - 5) ^ 2 * 3x + 1 ] - 2 + 7x
2 - 3 / [ (4 - 5) ^ 2 * 6 + 1 ] - 2 + 14
2 - 3 / [ (-1) ^ 2 * 7 ] - 2 + 14
2 - 3 / 7 - 2 + 14
2 - 2 + 14 - 3 / 7
14 - 3 / 7 = 13 4/7

Question: `q004
YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY
Your solution:
(x - 5) ^ 2x - 1 + 3 / x - 2
First you must replace the x’s with the number 4. (4 - 5) ^ 2 * 4- 1 + 3 / 4 - 2
Then you must follow the order of operations start with what is in parenthesis first.
(-1) ^ 2 * 4 - 1 + 3 / 4 - 2
Then you must work the exponents. 1 * 4 - 1 + 3 / 4 - 2.
Next you must work out the multiplication, followed by the division and addition and subtraction as they appear.
4 - 1 + 3 / 4 - 2
4 - 1 - 2 + 3 / 4
1 + 3 / 4 = 1 3/4

Question: `q005
YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY
Your solution:
X ^ 3x + 2 / x - 1
First you must replace the x’s with the number 2.
2 ^ 3 * 2 + 2 / 2 - 1
Then you must work the exponents. 8 * 2 + 2 / 2 - 1
Then you must work the multiplication. 16 + 2 / 2 - 1
Next you must work the division and addition and subtraction as they appear
16 - 1 + 2/2 16 - 1 + 1 = 16

Question: `q007
YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY
Your solution:
I think that expressions do not act the way most people would expect and they follow the laws of order of operations. It is important to understand the order of operations because just the smallest mishap with the understanding of the notation will cause all of it to be wrong.
