Step-by-Step Instructions
Step 1: Open Calculator Pro
Open the Side menu, then the Launcher, then tap Calculator Pro.
Step 2: Write an equation
Use the pen to write directly in the work area. For horizontal equations, write the full expression and add “=” at the end. For vertical sums, draw a long horizontal line under the problem. The answer appears automatically.
Step 3: Work with shapes and measurements
Tap Graphics to insert shapes like circles or triangles. Drag the anchor points to adjust the shape. Write values beside the sides or radius, then write:
- C= for perimeter
- S= for area
Step 4: Graph a function
Handwrite a function such as y = 5x + 3, then tap Generate Image / Insert Graph. Calculator Pro draws the graph so you can scale it and insert it into Whiteboard.
💡 Tip: Calculator Pro makes handwritten maths easier to show, explain and visualise on the spot.
Troubleshooting / What to Do If It Doesn’t Work
If Calculator Pro misreads your handwriting:
- Write larger and more clearly
- Leave space between numbers and symbols
- Use the correct layout for horizontal or vertical problems
- Try printed digits and symbols instead of cursive
