FAQ
›How does the calculator handle percentages?
Like a regular calculator: 200 + 10% = 220 (adds 10% of 200), 200 − 10% = 180 and 50 × 10% = 5. On its own, 10% is 0.1.
›Does it follow the order of operations?
Yes. Parentheses come first, then powers (^), then multiplication and division, then addition and subtraction. 2 + 3 × 4 = 14.
›Why does 0.1 + 0.2 give exactly 0.3?
Results are rounded to 12 significant digits, which hides the tiny errors computers make with decimal numbers.
›Are my calculations stored anywhere?
No. The calculator runs only in your browser and sends nothing.
