What happens when I divide by zero?

Division by zero is undefined in mathematics and will result in an error. This is because there's no number that, when multiplied by zero, gives a non-zero result.

How do I handle negative numbers?

The calculator handles negative numbers automatically. Remember: negative × negative = positive, negative × positive = negative, and similar rules apply for division.

What's the difference between × and * for multiplication?

Both × and * represent multiplication. × is the traditional mathematical symbol, while * is commonly used in programming and on computer keyboards. They mean exactly the same thing.

How precise are the decimal results?

The calculator provides results with high precision, typically accurate to many decimal places. For most practical purposes, the precision is more than sufficient.
