Quick answer: 1,250 × 4 − 300 ÷ 2 = 5,000 − 150 = 4,850: multiplication and division are done before addition and subtraction.
How it's calculated
Multiplication and division are done first, from left to right, then addition and subtraction. Brackets change the order: (1,250 × 4 − 300) ÷ 2 = 2,350.
A per cent sign divides by 100, so 15% × 200 = 30 and 50 + 10% = 50.1. Some handheld calculators read 50 + 10% as 50 plus 10% of 50 (55); here write 50 × 1.1 or 50 + 10% × 50 for that. To add or take off a percentage of a price, the percentage calculator shows each step.
Thousands commas (1,250) and Arabic digits are accepted. For powers, roots and trigonometry use the scientific calculator.

Frequently asked questions
Why is 2 + 3 × 4 equal to 14 and not 20?
Multiplication is done before addition: 3 × 4 = 12, then 2 + 12 = 14. Write (2 + 3) × 4 to get 20.
Can I divide by zero?
No. Division by zero is undefined, and the calculator says so instead of showing a number.
How do I work out fractions exactly?
Use the fraction calculator, which keeps results as simplified fractions such as 5/6.
How do I add VAT with this calculator?
Multiply by 1.15 for Saudi VAT, so 1,000 × 1.15 = 1,150. If you also want the VAT amount on its own, or to take VAT off a price, the Saudi VAT calculator does that.
Can I type Arabic digits?
Yes. ١٢٥٠ works just like 1250, and thousands commas are fine too.
What does the % sign do here?
It divides by 100, so 15% × 200 is 30. To add 10% to 50, type 50 × 1.1.
