General:  The arithmetic of lists is a very powerful tool, especially for elementary statistics taught by those who choose to go into detailed calculations of variance, standard deviation, and regression analysis. The calculators mentioned in the title can be used to perform all of the basic mathematical operations on all of the elements of a a list or of two lists.  Obviously, such operations as squaring all elements or multiplying the elements of one list by those of another, and even adding the elements of a list can save considerable time.  That save time can be used to learn important procedures rather than practicing arithmetic.   I.  Accessing List Tables:  Press STAT, ENTER and the lists will be displayed. II.  Clearing a list:  Move the cursor so that the name is highlighted and press CLEAR, then ENTER.  See Figure 1 below. Figure 1:  Clearing a list. III.  Entering Data:  Position the cursor where you want to enter data, enter the number, and press ENTER. IV.  Squaring the numbers in a list: Suppose we want to square the numbers in L1 and store the results in L3.   First position the cursor so that the name of the    destination list is highlighted (L3 in this example.).  Next press 2ND, L1,x², ENTER.  The operation will be displayed at the bottom of the screen.  (See Figure 2 below.)     Press ENTER to store the numbers in L3. Figure 2.  Storing squared L1 values in L3.  Ex: 2 Square L2 and store in L4:  Move the cursor to highlight the name of list L4. Press 2nd, L2, x².  (See Figure 3 below.)  Press ENTER to store the squared data in L4.   Figure 3.  Square y-values and store in L4. V.  Multiplying two lists:  Suppose we want to multiply two lists, for example “x” in L1 times y in L2, and store the results in L5.  Move the cursor so that the name for L5 is highlighted.  Press 2nd, L1,x (multiply sign),2nd, L2.  (See Figure 4 below.)  Now press ENTER and the products will be stored in L5 Figure 4: Multiplying L1 times L2. VI.  Getting the sum of a list:  You must first get out of the list Edit function by pressing 2nd, QUIT (the MODE key).  The list menu will be displayed.  Move the cursor over to MATH (see figure 5 below) and press 5 to paste “sum(“ to the home screen.  (See Figure 6 below.)  Now, press 2nd, L1 (the number 1 key), and ENTER.  The sum will be displayed as in Figure 6 below. Figure 5:   Display of list MATH menu. Figure 6:  Display of sum(L1. VII.  Getting the sums of the remaining lists:   You need not go through all of the steps again.  Merely press 2nd, ENTER to redisplay the entry for the sum of L1.  Now, position the cursor so that L1 is highlighted and press 2nd, L2 .  Press ENTER to get the sum of L2.  Repeat these steps for each list.  Part of the final screen is displayed in Figure 6 below. Figure 6:  Repeated summing of lists by re-displaying and editing a summation. Making it Better:  I would be grateful if you would report any errors or suggestions for improvements to me.  Just click "E-mail Webmaster," site the item number, and tell me your suggested change. Printing Hint:  Most browsers will send both the navigation bar and the text to the printer, and, as a result, some printers will cut off the right edge of this document  if  the file is printed directly.  To prevent this, you can use landscape, of course.   But if you'd like to get rid of the navigation panel,  highlight the instructions portion only (not the navigation panel) and check "Selection" on the Print dialog box; then click "Apply."  This will eliminate the navigation panel and get all of the instructions on the printed pages.  Some newer printers have a special Web Page function for printing that will print the page without cutting part of it off. Copy Restrictions:  You may make single copies of this document for your own personal use and for the use of other students, but inclusion in another document, publication,  or any use for profit requires my permission.  Teachers may make multiple copies of this document for their students if they first get my permission.  Merely send me an email (Just click on Webmaster in the navigation bar.) with a one-sentence explanation of what you’re using the document for.  I’ll give you permission in a timely manner.
