Question: `q004. Calculate (8 + 3) * 5 and 8 + 3 * 5, indicating the order of your steps. Explain, as best you can, the reasons for the difference in your results.
YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY
Your solution: (8 + 3) * 5: I would add 8 + 3 since it's in parenthesis then times that by 5. 11 * 5 = 55.
8 + 3 * 5 I would times 3 * 5 then add 8. 15 + 8 = 23.

Question: `q005. Calculate (2^4) * 3 and 2^(4 * 3), indicating the order of your steps. Explain, as best you can, the reasons for the difference in your results. Note that the symbol '^' indicates raising to a power. For example, 4^3 means 4 raised to the third power, which is the same as 4 * 4 * 4 = 64.
YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY
Your solution: (2^4) * 3 would be (2* 2 * 2 * 2) * 3 = 48
2^(4 * 3) is the same as 2 to the twelve power 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 = 4096.

Question: `q006. Calculate 3 * 5 - 4 * 3 ^ 2 and 3 * 5 - (4 * 3)^2 according to the standard order of operations, indicating the order of your steps. Explain, as best you can, the reasons for the difference in your results.
YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY
Your solution:
3 * 5 - 4 * 3 I would perform the exponent and multiplication first.
(4 * 3)^2 = 144
3 * 5 - 144= -129
3 * 5 - (4 * 3)^2
(4 * 3)^2 = 12 * 12 = 144
15 - 144 = -129

I higher the divided number is the less you will have. If you divide a number by a number greater then 1 the number will be smaller then the original one
