Frequently asked questions
Can I divide by zero?
No. Division by zero is undefined, so the calculator shows an empty result for it rather than displaying a value.
Does the calculator follow order of operations?
No — it computes one operation between two numbers at a time. If you have a longer expression, split it into steps and use the result of each step as the next input.
Can I use decimal or negative numbers?
Yes. Both operands accept decimals and negative values, so inputs like 3.5 ÷ −2 work just like whole numbers. The one refused case is division by an exact zero.
