How to use order of operations.
What does any kind of order have to do with math? It’s just left to right isn’t it? Wrong, the order of operations is a specific method to figuring out the correct answer to certain problems. For those of you who do not realize what I am yammering on about, this procedure piece is about the order of operations.
The order of operations is a method used to ensure that a group of people gets the correct answer without dispute, the order of operations is extremely useful. Without knowing the order of operations tell me, does this problem look sensible? 67-9(6-1)+48/ ((9x (5+2)-7’
Didn’t think so. The order of operations works like this: First anything in the parentheses, then we do the exponents/roots, then any multiplication and division- which is done in that order, then we do
Addition and Subtraction- in that order as well. To explain this, we will solve the problem above:
Step 1. The first thing you do in the order of operations is to do anything listed in parentheses, but you must also keep in mind everything else. So the first set we do is (5+2), even though it is the last set, addition comes first on the order of operation list. So, (5+2)= 7 right? Right, keep that in mind. Now we do the first set of parentheses, which is (6-1) which is 5. So replace both of those sets with (5) and (7) in that order.
Step 2. The next step is to get rid of those nasty square roots and exponents. So, first we do the square root of 9, which is 3. Then we perform the sacred exponent figuring. So 7 squared (7’) is 49. So by now the expression should look like this: 67-9 (5) +48/ 3x (7)-49.
Step 3. Now we multiply and divide all the stuff together so first we do 48/3, which is 16. Then we multiply what is needed, in this case it is 3x7, which is 21. Are you following me so far? Excellent if not then read it over.
In Brent Staples essay, Black Men, and Public Space the author talks about the ways he was discriminated against because of his race. In a few incidents when walking down the street many women thought because Staples was African American he must be a rapist mugger, etc. In addition, another
We still consider a black person as a bad individual in today’s society. In his essay, “Black Men and Public Space,” Brent Staples describes why he had to alter his behavior in order for the public to feel safe around him. Staples uses different examples in order for the reader to comprehend as to why he needed to do this. Staples further gives us details how he is being discriminated throughout all his life. Moreover, Staples tells us his emotions and frustration at how societal is prejudice towards black people. I agree he had altered his behavior because of the way society was treating him and how he lived day by day the injustices of society.
In the writing “Black Men and Public Space” by Brent Staples, located on www.learning.hccs.edu and published in 1986, the writing tells of a black man at the age of twenty-two who is viewed as a convict due to the prejudice wave consuming the United States. The publication opens with the young man walking the streets of Chicago during the dusk hours. A panicked woman walking ahead of him ran away. He was a black man with a beard, standing about six-two. His appearance made people nervous. He was seen as a rapist, mugger, criminal, and much worse due to how he was seen. Through this event, the author explains how the man was viewed during this period of time. Then, the man moved to New York City. Here, he felt the same discrimination. He was

This article is from The Journal of Experimental Psychology, and was written on an experiment performed by psychologist Bruce R. Ekstrand, from the University of Colorado. He experimented on the effects that sleep has on one's memory, after learning a particular bit of knowledge, in this case a certain list of twelve three-letter words.
... is clear that there is a broad amount of benefits to both the child and mother through the act of breastfeeding. Not only does it provide extreme health and psychological benefits, but it is also known to be economically benfecial as well. Mothers are able to save hundreds of dollars without the need to buy formula, and since breastmilk provides an adequate amount of nutrition that ultimately decrease a babies chances of sickness and disease, it is also known to save money from hospital fees as well. Medical care bills have been reported to be 20% less for families who excluvisely breastfed, compared to those who didn’t. (Health, 2003) It is clear that there are a handful of nutrional, physical, and psychological benefits that breastfeeing offers to both the mother and infant, compared to non-breastfeeding families, making it safe to say the breast really is best.
Strunk and White start their style guide off by reminding us of the rules of word order and punctuation. Rules that include: “Enclose parenthetic expressions between commas” and “The number of the subject determines the number of the verb”(2,9). These rules are not optional if you want others to understand what you are writing and your purpose for writing it.
Text Box: In the square grids I shall call the sides N. I have colour coded which numbers should be multiplied by which. To work out the answer the calculation is: (2 x 3) – (1 x 4) = Answer Then if I simplify this: 6 - 4 = 2 Therefore: Answer = 2
Children can enhance their understanding of difficult addition and subtraction problems, when they learn to recognize how the combination of two or more numbers demonstrate a total (Fuson, Clements, & Beckmann, 2011). As students advance from Kindergarten through second grade they learn various strategies to solve addition and subtraction problems. The methods can be summarize into three distinctive categories called count all, count on, and recompose (Fuson, Clements, & Beckmann, 2011). The strategies vary faintly in simplicity and application. I will demonstrate how students can apply the count all, count on, and recompose strategies to solve addition and subtraction problems involving many levels of difficulty.
First, consider expressions involving one or more arithmetic operations: addition, subtraction, multiplication, and division. The order of operations requires that all multiplications and divisions are done first, going from left to right in the expression. The order in which multiplication and division are calculated
The topic of time has always been one of interest to me at least on a philosophical basis. Through the works of Einstein, ancient timepieces and calendars such as Stonehenge, and even theories on past and present, time is everywhere. I chose this topic to perhaps explore further the relevance of clocks and timepieces in mathematics and arithmetic. To gain a better understanding of the mathematical features of time would be rewarding knowing that philosophy and mathematics are closely related.

For operations management to be successful, the function of the operation must be first be defined. The degree to which this is achieved is a measure of effectiveness, the key objective of operations management. Efficiency is less important since there is no point in which carrying out an irrelevant, or worse damaging, activity effectively. Effectiveness means achieving objectives, efficiency means consuming minimum resources. While both are desirable, the former is of overriding importance.
The early acquisition of mathematical concepts in children is essential for their overall cognitive development. It is imperative that educators focus on theoretical views to guide and plan the development of mathematical concepts in the early years. Early math concepts involve learning skills such as matching, ordering, sorting, classifying, sequencing and patterning. The early environment offers the foundation for children to develop an interest in numbers and their concepts. Children develop and construct their own meaning of numbers through active learning rather than teacher directed instruction.
