[. . . ] Enter the second element of the problem, and then press ¯. Tip If you make a mistake when you enter a number, you can correct it in one of the following ways. · Press s to delete the entire number. · Press _ to move the cursor to the incorrect number, and then enter the correct number. · Press ^ to delete the number at the cursor location. 2. Select FAST MATH from the SELECT A MODE screen. 5. 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. Addition No partial sums are shown in the standard 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. If the problem shows 1Ù9, the missing number can be 0 ­ 9. · In division problems, the remainder must be less than the divisor. · In division problems, the divisor cannot be 0. · There may be more than one correct answer. 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. When the game ends, the cumulative score is displayed. · The maximum score that is displayed is 50, 000. 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).
