<ol class="decimal">
<li id="li-1559"><p id="p-1622">From the Main Menu, instruct your student to space until scientific calculator is spoken or displayed. Press enter to open the calculator.</p></li>
<li id="li-1560"><p id="p-1623">On the Braille display, your student will feel the number 0.</p></li>
<li id="li-1561"><p id="p-1624">Use e with space to return to the Main Menu. A full cell with space will also get you back to the Main Menu.</p></li>
