Equation Solver - Taitham Numerals

What types of equations can the equation solver handle?

The equation solver can solve linear equations (e.g., 2x + 5 = 13), quadratic equations (e.g., x² - 5x + 6 = 0), polynomial equations, systems of linear equations, and general numerical equations. It supports both algebraic (symbolic) and numerical solving methods.

How do I use the quadratic equation solver?

Enter your quadratic equation in the form ax² + bx + c = 0 (e.g., "x^2 - 5x + 6 = 0"). The solver applies the quadratic formula x = (-b ± √(b² - 4ac)) / 2a to find all real and complex roots. For the example given, the solutions are x = 2 and x = 3. The discriminant (b² - 4ac) determines whether roots are real and distinct (positive), real and repeated (zero), or complex (negative).

How do I use the system of equations solver?

Use the linear system solver mode to enter multiple equations with multiple unknowns. For example, to solve (2x + y = 7, x - y = 2), the solver will find x = 3 and y = 1. The solver uses methods like Gaussian elimination or Cramer's rule. You can enter 2, 3, or more equations as long as the number of equations matches the number of variables.

How do I use the solve for x calculator?

Enter any equation containing the variable x and the solver will isolate x and compute its value. For example, enter "3x + 7 = 22" and the solver returns x = 5. For equations with multiple solutions (like quadratics), all valid values of x are returned. You can also enter equations with fractions, square roots, logarithms, and trigonometric functions.

Can I solve simultaneous equations with steps?

Yes. When you enter a system of simultaneous equations, the solver shows the step-by-step process: it forms the augmented matrix, performs row operations to reach row echelon form, and back-substitutes to find each variable. For example, solving 2x + 3y = 8 and x - y = 1 shows the elimination steps and the final answer x = 2.2, y = 1.2.

Can I solve 3 simultaneous equations with 3 variables?

Yes. Enter three equations with three unknowns (x, y, z) and the solver uses Gaussian elimination to find the unique solution. For example, the system x + y + z = 6, 2x - y + z = 3, x + 2y - z = 2 has the solution x = 1, y = 2, z = 3. The solver also detects when a 3-variable system has no solution or infinitely many solutions.

What is the difference between symbolic and numerical solving?

Symbolic solving finds exact algebraic solutions (like x = √2 or x = 3/4), while numerical solving finds decimal approximations (like x ≈ 1.414 or x = 0.75). For complex equations without closed-form solutions, numerical methods like Newton's method are used.

How do I solve an equation with no closed-form solution?

For equations like sin(x) = x or transcendental equations, use the numerical solver. Enter your equation, provide an initial guess (starting point), and the solver will iteratively find the approximate solution using numerical methods. The accuracy depends on the precision settings.

Can the solver handle polynomial equations of any degree with steps?

The solver can handle polynomials up to degree 4 (quartic) with symbolic solutions showing the formula steps, and higher-degree polynomials with numerical approximations. For cubic and quartic equations, it uses specialized formulas (Cardano's formula for cubics). For degree 5 and above, numerical methods are employed.

Can the quadratic equation solver find imaginary roots?

Yes. When the discriminant (b² - 4ac) is negative, the quadratic equation has two complex conjugate roots. For example, x² + 1 = 0 has roots x = ±i, and x² + 2x + 5 = 0 has roots x = -1 ± 2i. The solver displays complex roots in standard form a + bi. Switch to complex number mode for further operations with these roots.

Can I solve logarithmic equations for x?

Yes. Enter logarithmic equations like "log(x) = 2" (solution: x = 100) or "ln(x) = 1" (solution: x = e ≈ 2.718). The solver handles equations with log (base 10), ln (natural log), and logarithms with arbitrary bases. For equations combining logarithms with other functions, the numerical solver can find approximate solutions.

Can I solve two-step equations?

Yes. Two-step equations like 2x + 5 = 13 are solved by isolating x: subtract 5 to get 2x = 8, then divide by 2 to get x = 4. The solver shows these steps automatically. Two-step equations are common in pre-algebra and the solver handles them alongside more complex equation types.

Can I solve exponential equations?

Yes. The solver can handle exponential equations like 2^x = 8 (solution: x = 3) and 3^(x+1) = 81 (solution: x = 3). For equations where the variable appears in an exponent alongside other functions (like e^x = sin(x)), the numerical solver finds approximate solutions using iterative methods.

What should I do if the solver shows "no solution"?

This means the equation has no real solutions. For example, x² = -1 has no real solutions (but has complex solutions ±i). Check your equation for typos, verify it's mathematically valid, or try using the complex number mode if you need complex solutions.

Is the Tai Tham script still used in everyday life in Northern Thailand?

Not in everyday writing — Northern Thai speakers now use the Thai script for daily communication. However, the Tai Tham script remains in active use for Buddhist religious texts, temple inscriptions, and traditional manuscripts in Northern Thailand, Laos, and among Tai Lü and Khün communities. It is studied by monks, scholars, and cultural preservationists. The numerals appear in religious and historical contexts rather than in markets or government documents.

Input: Solve x² − 5x + 6 = 0

Result: Using quadratic formula: x = (5 ± √(25−24)) / 2 = (5 ± 1) / 2. Roots: x = 3 and x = 2.
