Learn more about privacyEveryone can do arithmetic. Almost nobody can do arithmetic on a long expression without losing track of the brackets, which is why the answer you get by hand and the answer the calculator gives so often disagree.
What Math Solver does
Evaluates a whole expression at once — brackets, powers, multiplication, division, addition and subtraction — with standard precedence.
Precedence is the entire point. 2 + 3 × 4 is 14, not 20, and a surprising number of spreadsheet errors trace back to somebody assuming otherwise.
How it reads an expression
| Order | Brackets, then powers, then × ÷, then + −, left to right within each level |
|---|---|
| Power symbol | ^ — so 3 ^ 2 is nine |
| Brackets | Nest as deep as you like; every opening one needs a closing one |
| Implicit multiplication | Not assumed — write 2 × (3 + 1), not 2(3 + 1) |
| Decimals | Use a full stop, whatever your locale writes |
| Division by zero | Reported as an error rather than returned as infinity |
Detailed steps
- Type the whole expression on one line.
- Use brackets wherever you are unsure — they cost nothing and remove all ambiguity.
- Read the result. If it surprises you, the bracket placement is usually why.
- Change one number and re-evaluate to see what drives the answer.
Worth knowing
The single most common mistake in this kind of expression is the minus sign in front of a power. Written strictly, −3 ^ 2 evaluates as −(3 × 3) = −9, because the power binds tighter than the negation. If you meant the square of negative three, you have to write (−3) ^ 2, which gives 9. Spreadsheets differ from mathematical convention here, which is exactly why the two disagree with each other so often.
Frequently Asked Questions
Why is 2 + 3 × 4 fourteen and not twenty?
Because multiplication binds tighter than addition, so the expression is read as 2 + (3 × 4). This is the standard convention everywhere from school algebra to programming languages, and it is why writing the brackets you mean is worth the two extra keystrokes even when you are confident.
Can I write 2(3 + 1) without the multiplication sign?
No — implicit multiplication is not assumed, because it is genuinely ambiguous in longer expressions and different systems resolve it differently. Write 2 × (3 + 1). The strictness is deliberate: an expression that could be read two ways is worse than one that has to be typed out.
What does the ^ symbol do?
It raises to a power, so 3 ^ 2 is nine and 2 ^ 10 is 1,024. Note that it binds more tightly than a leading minus sign, so −3 ^ 2 gives −9 rather than 9. If you want the square of a negative number, put it in brackets.
Does it handle very large numbers exactly?
Up to a point. It uses standard double-precision floating point, which is exact for integers up to about 9 quadrillion and then starts rounding. It also inherits the familiar decimal artefacts — 0.1 + 0.2 lands just above 0.3 — which matter for money calculations and almost nowhere else.
Is Math Solver free?
Yes. The Vootkit free plan includes 5 tool runs a day. Upgrade to Vootkit Pro for unlimited daily use, an ad-free workspace and saved workflows.
Are my files uploaded?
No. Math Solver runs entirely in your browser — your file is processed on your own device and never sent to a server. There is nothing for us to store or delete.
Do I need to install anything?
No. Math Solver works in any modern browser on desktop, tablet or phone. Open the page and start.
How often can I use it? Is there a daily limit?
On the free plan you get 5 tool runs a day. When you reach the limit you'll see a prompt to upgrade, and it resets the next day. Vootkit Pro removes the cap entirely for unlimited daily use.
