TI-73 / TI-83 Plus Math by Hand Application Page 4 Where to Find Installation Instructions Detailed instructions on installing this and other applications are available at education. ti. com/guides. [. . . ] Select START to solve the problem. Tip Select FASTER to display the solution more quickly. TI-73 / TI-83 Plus Math by Hand Application Page 14 The examples below show the standard fast algorithm. Notice that the 1 is carried to the tens place above the 3. Subtraction Subtraction in Fast Math mode is similar to subtraction in Step-by-Step mode. No text is displayed on the screen to explain the steps. TI-73 / TI-83 Plus Math by Hand Application Page 15 Multiplication Multiplication in Fast Math mode shows the shortcuts that students can use with this algorithm. Notice that 3 " 12 and 20 " 12 are displayed as partial products, which is a compression of the steps shown in Step-by-Step mode. TI-73 / TI-83 Plus Math by Hand Application Page 16 Division Division in Fast Math mode shows the shortcuts that students can use with this algorithm. To see the answer in fraction form, select FRAC. If the fraction can be simplified, the simplified value is also shown. TI-73 / TI-83 Plus Math by Hand Application Page 17 Using Missing Pieces Mode Missing Pieces mode is a quiz that challenges you to fill in the missing place values in a problem. Keep in mind the following rules as you play the game. · Enter the missing values, and then press ¯ to check your answer. · After you check your answer, press ¯ to display a new problem. · Use _ and a to move the cursor to the next missing place value. · A leading zero is never a correct answer for a missing place value. For example, if the problem shows Ù9, the missing number can be 1 ­ 9. · In division problems, the remainder must be less than the divisor. The TI 83 Plus checks your answer to verify that it is correct. TI-73 / TI-83 Plus Math by Hand Application Page 18 You score points based on the difficulty of the problem and how quickly you fill in the missing pieces. Tip · When your score exceeds a multiple of 10, 000, the score counter is restarted. You can continue playing after your score exceeds 50, 000, but the score will not change. At the beginning of the game, you have three lives (lives are the number of opportunities you have to continue playing the game if you give an incorrect answer). When your score first exceeds 500 points, you earn one extra life; after that, you earn an extra life each time you score 2000 more points. Tip The game displays a maximum of three lives, but you can earn additional lives. TI-73 / TI-83 Plus Math by Hand Application Page 19 Press a to move the cursor to this missing place value. Number of lives remaining (dots) and your current score Animated hourglass Amount of time remaining to solve this problem Missing place value at the current cursor location Displays the game instructions. Press any key to return to the game. Returns to the SELECT A MODE menu. TI-73 / TI-83 Plus Math by Hand Application Page 20 Deleting the Application TI-73 1. Memory Error This error occurs when the TI-73 does not have sufficient memory for the application. In order to make room for another application, you must delete an application from the TI-73. Before you delete an application from the TI-73, you can save it on your computer using TI Connect software or TI-GRAPH LINK software for the TI-73. You can reload it to the TI-73 later using TI Connect or TI-GRAPH LINK software. Other Errors See Appendix B in the TI-73 guidebook or pages B-6 through B-10 in the TI-83 Plus guidebook for information about the specific error.
