Most individuals have the option of buying a liter of soda, or a twelve pack. They begin to ponder over the thought of which is the better buy. Simply looking at the price may or may not help. Whichever is the least expensive buy, they are sure to go after that one. Sometimes checking the quantity helps also. If the twelve pack has a greater quantity, that would most definitely be better, simply because the liter bottle only has a liter worth of soda. Things should be taken into great consideration when buying items, or you could be cheated out of your money. Even when comparing two brands together, the quality, and price should be looked upon. If you had two brands to pick from, one has a better quality and is slightly more expensive, or the cheap quality one, that is not as expensive.
         Back to the soda problem, which is the better buy? Well I believe that the liter is the better buy, because if you had a twelve pack it would be similar to that of buying each one individually. Sales is also an issue in these items. One might be one sale, and have a slightly cheaper price then the other, but if they were both on regular sale, I would definitely got with the liter. You can even experiment with using empty glasses to pour the liter in. Take in consideration, that you have twelve glasses, each about the size of the soda cans in the twelve pack. Then you can pour the liter of soda into each of the cups, making sure you get the measurement precisely. If the liter fills all twelve cups, then you can infer that the liter is most likely the better buy.

Great and hard challenges were identified throughout the course of this past semester. Memories also came with this past semester. Exponents, word problems, and factoring were main key points. I found that these lessons were the most important in regards to this past semester. For review, exponents were known as "the power to." Factoring could be easily done with a factor tree, and finally word problems. Word problems were the hardest for me to comprehend, simply because of the complicated procedures needed. I can say that I definitely remember the word problems the most. Some were easily solved, and the rest seemed to be harder. I never fancied the word problems much, but the majority helped me with the lesson.
          In all regards, this past semester had its difficulties, and easy points. Challenges weren't as they seemed, and most had to be taken into caution. Each memory had a significant reason behind it. The Pythagorean theorem should be remembered by all students, simply because it can be used with more sophisticated maths in the future. Finding one length on a right trianle is one
