Making formulas Like your calculator, you can use Excel to perform many mathematical functions as well as organize data In this module we will work on some basic activities to get us started, then work on two major assignments.
CommandFunction ^Exponentiation *Multiplication /Division +Addition -Subtraction >Greater Than
More stuff Constants are numbers that remain unchanged in the formula. For example, in =2+3 the numbers 2 and 3 are constant. The only way to change this is to edit the formula Variables are values with numbers that can vary or change according to how you set them up
Activity 1 Open a blank excel document Type in the number 12 in cell B4 and 144 in C4 Click on cell D4 Type = Type the formula to multiply the two numbers (B4*C4) Press Enter Save it as Activity 1
Activity 2- recreate this table ABCD 1Monthly Budget 2 3ExpensesJanuaryFebruaryMarch 4 5Rent500 6Food Phone Utilities Car Loan350 10Gasoline
Activity 2- Next Steps 1.Enter the label “Total Expenses” into cell A11 2.Type into cell B11: =B5+B6+B7+B8+B9+B10 3.Press Enter to end the formula. Do this for the other categories 4.Enter the total for cells C5 and C10 in cell C11 5.Change the monthly food bill for February to 240. See what happens. 6.Save this as Activity 2 Note: Excel reads equations using BEDMAS
Functions There are over 200 functions in Excel. Here are some examples: =Average(B6:C6:D6) would calculate the average spent on food in the graph =sum(B6:C6:D6) adds them all together
Functions To enter functions: 1.Click the cell where you want the formula 2.Type an equal = sign 3.Type the function name i.e. Average 4.Type in brackets the values you want to use 5.Press Enter Horray! Are you a wizard?
Activity Open Activity 2 2.Add the title Quarterly Report in cell C1 3.Enter the label “Total” in E3 4.Enter the formula =SUM(B5:C5:D5) in cell E5 5.Total the other rows 6.Save your work, replacing the original Activity 2
Activity Enter Average in cell F3 2.Enter Maximum in cell G3 3.Enter Minimum in cell H3 4.Enter =AVERAGE(B5:D5) in cell F5 5.Enter =MAX(B5:D5) in cell G Enter =MIN(B5:D5) in cell H5 7.The values in F5, G5 and H5 should be 500. Do you see why? 8.Save your work
Activity 2-4 Replace the cell contents of B11 with =SUM(B5:B10) Edit C11 so it reads =SUM(C5:C10) Edit cell C1 to read “Quarterly Report 2012” Edit the Utilities for March to 205 Delete the contents of cells in the range E6:H10
Activity Move the contents of cell A11 into A12 2.Move the contents of cells B11:D11 down to B12:D12 3.Copy the formula in cell E5 into E6 4.Copy the formula in cell E6 into the range E7:E10 5.Copy the formulas in the range F5:H5 into the range F6:H10

Assignment 1 You will get to create your own monthly budget system, using our template Imagine that you are living on your own and are attending college in Edmonton while working part-time. You will have to research the cost of food, living expenses, travel, entertainment and other expenses to determine your monthly budget
Assignment 1 You will have to create specific columns for the things you would spend money on Create columns for rent, food, transportation, entertainment, clothing, and miscellaneous You will also have a columns for you earnings from your part-time job and a column for the money used from your savings
Details You work part-time. You are paid every two weeks. You make $500 every two weeks working at the Unforgettable Chinese Restaurant You have to pay 60 dollars a month for a bus pass You go shopping for food once every week. Find out how much it costs to properly feed yourself over a week. Your rent is $480 a month. You have a room mate. It’s too bad he smells, but at least you are splitting the rent. Your tuition costs $433 a month You spend $20 a week on entertainment/ eating out Your Shaw phone and internet bill is $70 a month You withdraw $20 from an ATM every month
Details Before you left for the city, you saved $600, but your apartment was unfurnished, so you have to buy a bed, linens, dresser, cleaning supplies, desk etc. research the cost and put this in your budget under “other” This spreadsheet you will make will cover 3 months.
How Do I Do This? Copy this EXACTLY as shown. I had to split the picture in two
How much you spent on something How much you got paid or made Your overall balance
How much you spent on something How much you got paid or made =F11-D12+E12 FORMULAS So this takes your current balance, subtracts the last payment you made (D12), and adds in any money you may have made (+E12) Copy this formula down the column
Keeping Track If you buy something, record it’s price in the appropriate column. Record the date and whereabouts of an item you have purchased in this column Record the amount for the item here as well. This is important because this is for the formula
Keeping Track More If you take any money out, record this here then put it in the Amount Paid column too This is for cheques. Your rent will have to be paid in cheques
Way Down Low Make this down at the bottom all the way across to the T Column. The bottom Row that you see is down at Row 123. We will use this to record what happens at the end of the month
Formulas! Here, use a Summary formula for all of the G columns that are used. Here, put =N13. Then copy the formula down. The N column is where we record anything put in your savings This column represents Your budget This column shows your total expenses
Formulas! Create a sum of everything used in the R column. Create a sum of everything in the T column
The Budget Once you think you know how much everything costs, estimate how much it will be by putting it in your budget column. Where the Zeroes are in this picture.
Under or Over Budget? R9- R123 T9- T123
Starting Next Month In this cell enter this formula. It will carry over your money from last month. Repeat for the next page with this month.
Life Comes At You Fast! Include the following in your expenses: In January you unexpectedly caught fire. You no longer have a nice pair of jeans and have to buy another. In February you went out with your friends for dinner and spent $50. In March you had to take a cab. Add $40 to this month
Figure Out: 1. How much do you have left over in your chequing account at the end of 3 months 2. Your total savings for 3 months 3. How much you spend in a month 4. How much you can budget in each category monthly (the part at the top of the sheet with the categories) 5. Assuming your budget is the same for the next 8 months, what will your savings, earnings and expenses look like? 6. How much can you put in your savings at the end of the month Include this information in a separate Word document to hand in as well. Call your document Lastname.Firstname Spreadsheet 2
Save and Hand In!!! Don’t forget to make this for 3 months As with all Info credits, you need to write a 1- page reflection on this assignment, double- spaced. Discuss what you found difficult or easy with this assignment. Also discuss how this assignment relates to careers and life experiences. The end!
