That’s on you. You should define if it’s a string or an integer.
It’s even worse. They’re teaching him JavaScript.

If your salary is 20k/yr and you sent your son to a 25k/yr school the math skills are genetic
Dept exists?
So does spending beyond your means. Give your kid a better life as you are able. Don’t sink your own ship to save a man overboard, there’s always a way.
You mean debt? Yes, why?
Because it allows to give your child a better education than your current salary would otherwise allow.
Doesn’t work like that. No bank is going to give you a 25k/yr loan for your child’s education on a 20k/yr salary.
Also: it was a joke.
Maybe he’s learning JavaScript?
Don’t let your kids learn about string concatenation
You’re already paying for public schools. Might as well use them
Iirc, you use || for that operation. There’s a couple of numberphile videos about that.
