Today I bought a simple calculator, but later on i noticed on the box that it has "key tone". It doesn't beep tho. I looked inside and there doesn't appear to be any extra wire so I guess it won't beep? Why am I asking such a question? Let's just say that if this beeped on my test in school nothing good would come from it...
