I don't really think I missed anything. If i did, I don't know how to explain it.
If you don't use the order of operations then you will not get the correct answer. Using powers to solve problems helps us solve the problems faster. We use roots to solve problems by seeing if a number is a perfect square or not. We use scientific notation to solve problems by using the power of ten. A rational number is a number that is a perfect square and it is not a decimal that repeats. An irrational number is not a perfect square and it never ends. They are used to solve problems to see if its a perfect square or not. The absolute value is the distance from zero. It can never be a negative number. Ratios and proportions are used to solve real world situations by comparing one thing to another. Ratios and proportions are also used to find percents. For proportions, you cross multiply. You estimate the numbers in a problem to numbers that are close and are easily divided by each other. All these things will probably apply to me in the future because i want to be a teacher.
