Hey @nerxxy!
Your explanation of what you want is really confuse, it took me more than 5 reads to understand, please be clearer in the future, otherwise we won’t help!
From what I understand, if the result is higher than a specific number you want a 30% chance the response to be “math is hard”, and if the result is lower than the same specific number you want a 50% chance the response to be “math is hard.”
Did I get that right? See how concise and easier to understand it is? That’s how it should have been. And in case English isn’t your native language, so it isn’t mine either.
Anyway, back to the command:
$(eval r=Math.floor(Math.random()*10)+1; m=$(urlfetch http://twitch.center/customapi/math?expr=$(querystring)); if(m>SPECIFIC_NUMBER){r>7?`Math is hard.`:`${m}`}else{r>5?`Math is hard.`:`${m}`})
Replace SPECIFIC_NUMBER by the number of your choice and you’re good to go.
