The Basic Calculator does everyday arithmetic: addition, subtraction, multiplication, division, powers and percentages, following the normal order of operations. For trigonometry and more, use the Scientific Calculator.
12 + 7 × 3 − 8 ÷ 2 = 29
| Result | 29 |
Type an expression with numbers and the operators + − × ÷ (or * and /), ^ for powers, % for percent and parentheses for grouping, then click Calculate.
Calculations follow PEMDAS/BODMAS: parentheses first, then exponents, then multiplication and division from left to right, then addition and subtraction from left to right. 12 + 7 × 3 − 8 ÷ 2 = 12 + 21 − 4 = 29.
50% is read as 0.5, so 200 × 15% = 30. To add a percentage, multiply by (1 + rate): 200 × 1.15 = 230.
Why is 2 + 3 × 4 not 20? Multiplication comes before addition.
Can I use decimals? Yes.
What happens if I divide by zero? The result is an error.
