-Whether you are an Ink user or prefer to type your math as text, Math Assistant can: 
-*	give your students step-by-step instructions on how to solve their math problems. 
-*	help them visualize math functions on an interactive 2D graph.
-This digital tutor is available in the OneNote app for Windows 10 and OneNote Online.
+The **Math Assistant** and **Ink Replay** features available in the OneNote app for Windows 10 and OneNote Online give your students step-by-step instructions on how to solve their math problems and help them visualize math functions on an interactive 2D graph.
 
-**Try this in OneNote!**
-To solve x^2-3x+2=0:
-1. Write your equation in ink or type it as text. Use the **Lasso** tool to select the inked equation (or select the text if you typed it) and then, on the **Draw** tab, click the **Math** button.
+**Let's solve 3x+4=7 in OneNote using the pen!**
+To get started:
+1. Open the OneNote app for Windows 10 (not OneNote 2016).
 
-2. From the drop-down menu in the Math pane, select the option to **Solve for x**. You can now see the final solution of the equation.

-5. On the **View** tab, click the **Replay** button and select the written equation to watch it replay your text. 
+3. Click **Add Page** to launch a blank work space.
 
-To graph y=sin(x):
-1. Write your equation in ink or type it as text (make sure the "y" isn't capitalized). Use the **Lasso** tool to select the inked equation (or select the text if you typed it) and then, on the **Draw** tab, click the **Math** button.
+  ![Select add page button](images/plus-page.png)
 
-2. From the drop-down menu in the Math pane, select the option to **Graph in 2D**. 
-  >You can play with the interactive graph of your equation - use a **single finger** to move the graph position or **two fingers** to change the zoom level, or use a mouse to **click and drag** to move the position or use the **magnification** buttons to change the zoom level.
