- To start, drag out a number. Join numbers together if a longer starting number is required.
- Drag out a symbol and attach it to the number.
- Drag out another number and attach it to the symbol. Again, numbers can be attached together first as a separate process if longer numbers are required.
- Click or tap the ‘?’ to reveal the answer
It is possible to change the sum by replacing symbols or numbers by dragging them on top.
To delete a sum, drag it to the trash can.
