this is the project I have creates for kids. My issue is that while I subtract like 20-40 the answer is -20. but while saying the output as voice it skips the negative sign and just saying 20.
please guide me if any one of you know the answer.

TTS probably thinks the - is a hyphen.

Use a text replacement block to replace - with minus (there is a space after the s)

If it's necessary, you'll need to export your project's .aia and import it here:
