You will see a cursor blinking in the upper left corner of the Home screen. Press 2ndON to turn #emph[off] the calculator. === Numbers and Operations The parentheses keys, the Clear key, and the Enter key are shown in Figurea. Locate the number keys, operation keys, and arrow keys on your calculator, as shown in Figureb. We use the key for subtraction, but we use the (-) key (located next to ENTER) for negative numbers. #examplebox("Example 1")[][ Compute #math.equation(block: false, alt: "5 minus 8")[$5 − 8$].

Press CLEAR to clear the contents of the current input line. In the Home screen, press CLEAR CLEAR to clear the entire screen. ==== Troubleshooting + If your screen is too light, press 2nd several times to make it darker. If it is too dark, press 2nd . + For the features we use in this book, the MODE and FORMAT should be in their default settings. Press MODE to see the menu in Figure B.2a, and 2nd ZOOM to see the format menu in Figureb. Use the Arrow keys and ENTER to alter the menus to the default settings if necessary. #emph[Note]: The Set Clock function does not appear on the T1-83.#figure(figph[GC windows of settings], alt: "GC windows of settings", caption: none)
