0:00:00.190,0:00:03.727 To start this unit, we'll look at Math Quill so you can input exponents and 0:00:03.727,0:00:07.582 scientific notation with ease. You might have already discovered how to enter 0:00:07.582,0:00:11.468 exponents using Math Quill, and even if you haven't here's a quick walk-through 0:00:11.468,0:00:15.404 on what to do. First you want to type the letter x, this will create an x in 0:00:15.404,0:00:19.774 your math quill box. Then you want to type carrot symbol, you notice that right 0:00:19.774,0:00:23.862 before you type the carrot symbol your cursor bar will appear after the x. 0:00:23.862,0:00:28.096 Immediately after you type the carrot key, the cursor bar will move up and in 0:00:28.096,0:00:32.685 the position for an exponent, or a superscript. You will then type the number 4 0:00:32.685,0:00:36.419 to get the 4 as the exponent. And here's where you can run into trouble. If you 0:00:36.419,0:00:41.230 keep continue typing, you will be typing exponents or powers. To move the cursor 0:00:41.230,0:00:44.600 bar back down to the main line, you want to hit the right arrow key. Hitting the 0:00:44.600,0:00:48.632 right arrow key gets us to the main line and now it continues typing the rest of 0:00:48.632,0:00:52.712 our expression. So finish entering this expression, and then try these other 0:00:52.712,0:00:57.008 ones. There's also a challenge problem down here. It contains both an exponent 0:00:57.008,0:00:58.163 and a fraction.
