...Constructing Formulas for Mathematical Operations in Excel (Basic Tips and Techniques) Michelle A. Applequist Computer Information Systems (CIS105) Professor Hari Dhungana Strayer University September 1, 2009 Constructing Formulas for Mathematical Operations in Excel Microsoft Excel uses formulas to construct mathematical operations in a worksheet. After data have been entered into the worksheet, you can perform calculations, analyze data, and create charts. An Excel formula (calculations you create) and functions (formulas pre-existing in Excel) calculates the data entered in the worksheet. Formulas calculate numbers in a particular order. “Excel has one of the most comprehensive set of formulas, not only to perform calculations but also to manage data and records. It also has the ability to instantaneously re-calculate the results as the raw data changes” (Khoo, 2006-9, para. 2). To construct a formula after you have entered data, you must click in the cell that you want the results to appear in, and then type the formula. You can construct formulas by using the sum function, and editing numbers in a cell. It is stated that: Sum is an Excel function—a prewritten formula. Sum indicates the type of calculation that will take place (addition). When the sum function is activated, Excel looks above the active cell for a range of cells to sum. If there is no range above the cell, Excel will look to the left for a range of cells to...

...at a university. Your task is: 1. Using IF, filter the data for these students by major. You will need to add a column for each major and then use the IF function to filter the data by major. Your formula should use proper anchoring so it is copyable both down and across. 2. Calculate the overall average GPA as well as the average GPA for each major. 3. Use conditional formatting to shade cells pink if a GPA is less than 2.2 Your solution must look like this (including the formatting): Your solution must take into account the possibility that the data could change, i.e., do not “hard code” any data values. If the major of a student changes, your calculations should update to the correct values automatically. Additionally, if new rows are inserted or existing rows are deleted, your spreadsheet model should still work.

...be astronomical as long as the process is correctly developed. Cellonics is the future. Transmitting data over radio waves and then defragmenting is soon to be a method of the past, Cellonics offers technology with the ability to increase modem speed by up to 1000 times. The breakthrough came from the study of human cells, when stimulated these cells generated waveforms separated by periods of silence. The Cellonics technology has developed a procedure which mimics these signals in a way in which they can be applied to the communications industry. This sophisticated technology accepts slow analog input and distributes rapid pulse waveforms encoding digital information and broadcasting it over communication channels. NDS mathematical formulas are applied to the cells to stimulate responses; this is a non-linear system so the output can exceed normal capacities while the application remains straightforward. Cellonics is set to revolutionize the communication industry. Businesses or corporations which communicate remotely will be able to increase their speed, reliability and decrease their power consumption. All of these factors combine to offer a lower overhead operating cost and in return a higher profit margin. The face of telecommunications is changing, Cellonics is leading the charge.

...Math Investigation of Painted Cubes Introduction I was given a brief to investigate the number of faces on a cube, which measured 20 small cubes by 20 small cubes by 20 small cubes (20 x 20 x 20). To do this, I had to imagine that there was a very large cube, which had had its outer surface painted red. When it was dry, the large cube was cut up into the smaller cubes, all 8000 of them. From there, I had to answer the question, 'How many of the small cubes will have no red faces, one red face, two red faces, and three faces? From this, I hope to find a formula to work out the number of different faces on a cube sized 'n x n x n'. Solving the Problem To solve this problem, I built different sized cubes: 2 x 2 x 2; 3 x 3 x 3; 4 x 4 x 4; 5 x 5 x 5; 6 x 6 x 6; 7 x 7 x 7; 8 x 8 x 8; 9 x 9 x 9, using multi-links. I started by building a cube sized '2 x 2 x 2'. As I looked at the cube, I noticed that all of the corners had three faces. I then went onto a '3 x 3 x 3' cube. As I observed the cube, I saw that the corners all had three faces, the edges had two, and the faces had one. I looked into this matter to see if this was true. As I went further into the investigation, I found this was true. This made it much easier for me to count the cubes, and be more systematic. Now I could carry on building the cubes, and be more confident about not missing any out. Whilst building the cubes, I also drew them and decided to color code the different faces...

...Mathematical Writing by Donald E. Knuth, Tracy Larrabee, and Paul M. Roberts This report is based on a course of the same name given at Stanford University during autumn quarter, 1987. Here’s the catalog description: CS 209. Mathematical Writing—Issues of technical writing and the effective presentation of mathematics and computer science. Preparation of theses, papers, books, and “literate” computer programs. A term paper on a topic of your choice; this paper may be used for credit in another course. The ﬁrst three lectures were a “minicourse” that summarized the basics. About two hundred people attended those three sessions, which were devoted primarily to a discussion of the points in §1 of this report. An exercise (§2) and a suggested solution (§3) were also part of the minicourse. The remaining 28 lectures covered these and other issues in depth. We saw many examples of “before” and “after” from manuscripts in progress. We learned how to avoid excessive subscripts and superscripts. We discussed the documentation of algorithms, computer programs, and user manuals. We considered the process of refereeing and editing. We studied how to make eﬀective diagrams and tables, and how to ﬁnd appropriate quotations to spice up a text. Some of the material duplicated some of what would be discussed in writing classes oﬀered by the English department, but the vast majority of the lectures were devoted to issues that are speciﬁc to mathematics and/or computer science.

...day. I guess you can say that this is where my love for math started. I am not saying that I never had to study or that I have never struggled with any math in my life, but for the most part, most of the math classes I have taken in my life have come pretty easily to me. I love when you are struggling with something in math and all of a sudden you have that a-ha moment where everything suddenly makes sense. In the past I have taken all the basics in math including Algebra and Geometry. However, these courses were also taken almost 20 years ago, and I have to admit that I am a bit rusty when it comes to all of the formulas and properties. Even though I may not remember all of the formulas, I still consider my previous courses a success. I may not remember the exact formula, but I do remember that the formulas exist and it is just a matter of looking the formula up and plugging in the right numbers to get the correct answer. For example, I remember how I used to love doing proofs in geometry, the longer the better. I probably could not jump right into one of those long proofs now, but I don’t think it would take me long to get back to being able to solve one. This is because math is always the same. It is not like English where the rules are always changing. Two plus two will always be four, and this is...

...- c(1-t) + m ] = c0 + I + G + X Denoting the RHS (the sum of the autonomous components) with the symbol A, we have Y = 1 / [1 - c (1-t) + m]* A which gives us the equilibrium level of national income, but can also be expressed as changes: ΔY = 1 / [1 - c (1-t) + m]* ΔA The expression { 1 / [1 - c (1-t) + m] } is the multiplier (K). Dividing both sides of the above equation by ΔA ECON 1002 Feb 2013 We have ΔY / ΔA = 1 / [1 - c (1-t) + m] which gives us our first formula for K. What about the second formula? What is z? It is the marginal propensity to spend out of national income, which include the propensity to consume and the propensity to import. As we saw above, consumption spending comes out of disposable income, and therefore, the propensity to consume out of national income is c(1-t). We also assumed that imports represent a leakage from the circular flow, therefore, – m represents the propensity to import. We therefore have z = [c(1-t) – m] Notice that the minus sign in front of z in the multiplier formula will change the sign of its two terms and gives us the exact expression of K we derived above. What is obvious from the multiplier? From this expression we derived for K, we see that when c increases, the multiplier will increase, and when t and m...
