Online Math Equation Solver
Solve any math expression with order of operations, exponents, parentheses, and built-in functions.
Use numbers and + - * / ^ root(x[,n]) ( ) [ ] { }
Answer
-490
What Is This Tool?
The Math Equation Solver evaluates a typed expression and returns the answer, following the standard order of operations. It supports addition, subtraction, multiplication, division, exponents, parentheses, and functions like square roots and trigonometry. For example, (10+5^2)((5*-2)+9-3^3)/2 evaluates to -490.
How to Use This Tool?
- Type your expression in the input box.
- Use ^ for powers and * for multiplication.
- Use parentheses to group terms.
- Click Calculate to see the result.
Key Features
- Follows the correct order of operations.
- Handles exponents, parentheses, and nested brackets.
- Understands implied multiplication like (2)(3).
- Includes roots, logarithms, and trigonometric functions.
- Reports a clear error for invalid input.
Examples
- 2 + 3 * 4 = 14, because multiplication comes first.
- (8 - 3)^2 = 25.
- sqrt(144) = 12.
- (10+5^2)((5*-2)+9-3^3)/2 = -490.
Common Use Cases
- Checking multi-step arithmetic quickly.
- Evaluating expressions with exponents and roots.
- Confirming the order of operations in homework.
- Working through algebra and pre-calculus practice.
- Computing values that involve functions like log or sin.
Tips & Best Practices
- Use parentheses to make grouping explicit.
- Write ^ for exponents, as in 3^2 for three squared.
- Trigonometric functions use radians, not degrees.
- Avoid dividing by zero, which has no defined result.
- Double-check that every opening bracket has a closing one.
Limitations
- It evaluates numeric expressions, not equations with unknowns.
- Trigonometric functions work in radians.
- Results that are infinite or undefined are rejected.
- Very long decimals are rounded for display.
Frequently Asked Questions
- What is the order of operations?
- Operations are evaluated in this order: parentheses, exponents, multiplication and division, then addition and subtraction, working left to right.
- What operations and functions are supported?
- It supports +, −, ×, ÷, exponents, parentheses, and functions such as sqrt, root, log, ln, exp, and the trigonometric functions.
- Does it understand implied multiplication?
- Yes. Expressions like (2)(3) or 2(3) are read as multiplication, giving 6.
- Why did I get an error?
- An error usually means a typo, a missing bracket, an unknown function, or a result that is undefined, such as dividing by zero.
Key Terminology
- Expression
- A combination of numbers, operators, and functions that evaluates to a value.
- Order of operations
- The rules that decide which parts of an expression are calculated first.
- Exponent
- A power that shows how many times a base is multiplied by itself.
- Operator
- A symbol such as +, −, ×, or ÷ that performs a calculation.
- Parentheses
- Brackets that group terms so they are evaluated together first.
