Step-by-Step Instructions
Step 1: Write more clearly
Make your handwriting a bit larger and neater so the tool can recognise the symbols more accurately.
Step 2: Leave space between symbols
Do not crowd numbers and operators together. Leave space between digits and symbols.
Step 3: Use the correct layout
For horizontal equations, write the full expression and add “=” at the end. For vertical sums, draw a horizontal line under the problem.
Step 4: Try printed characters
If you usually write in cursive, switch to printed digits and symbols.
💡 Tip: Clear handwritten input gives faster results and helps the graphing tools work more reliably.
Troubleshooting / What to Do If It Doesn’t Work
If the answer or graph still does not appear, restart Calculator Pro and try again. Then log a ticket on the Support Portal at Knowledge Base if needed.
