Math & Science Calculators

Math and science calculators serve as essential tools across education, engineering, and research. The Basic Calculator handles everyday arithmetic (addition, subtraction, multiplication, division) with a simple interface that mirrors physical calculators. Use it for quick calculations, checking homework answers, balancing budgets, or any situation requiring standard math operations.

The Scientific Calculator extends functionality to advanced mathematical operations essential for STEM fields. Trigonometric functions (sin, cos, tan) solve angle problems in physics and engineering. Logarithmic and exponential functions appear in chemistry calculations, population models, and financial growth equations. The calculator handles order of operations automatically, supporting parentheses for complex expressions.

Fraction Calculator eliminates the common frustration of manual fraction arithmetic. Adding fractions requires finding common denominators, while multiplying and dividing involve additional steps that are error-prone by hand. This calculator handles all fraction operations, simplifies results automatically, and converts between mixed numbers and improper fractions. Essential for cooking (recipe scaling), construction (measurements), and mathematics education.

Square Root Calculator computes roots beyond simple whole numbers. While calculators can find √16 = 4 easily, this tool handles irrational roots like √7 with precision to many decimal places. It also calculates nth roots (cube roots, fourth roots, etc.) necessary in geometry, physics equations, and engineering formulas. Use it for finding dimensions, solving quadratic equations, or any application requiring root extraction.

Statistics Calculator transforms raw data into meaningful insights. Input a dataset to instantly compute measures of central tendency (mean, median, mode) and dispersion (range, variance, standard deviation). These statistics appear everywhere: analyzing test scores, understanding survey results, quality control in manufacturing, and scientific research. The calculator handles large datasets and shows intermediate steps for educational purposes.

The Equation Solver handles three types of equations commonly encountered in algebra and engineering: linear equations (ax + b = c), quadratic equations (ax² + bx + c = 0) with discriminant analysis for real and complex roots, and systems of two linear equations using Cramer's rule. This eliminates the tedious algebra steps while providing full solutions including complex number results when applicable.

Matrix Calculator performs essential linear algebra operations on 2×2 and 3×3 matrices. Addition, subtraction, multiplication, transpose, determinant calculation, and scalar multiplication are all available through a visual grid-based interface. These operations appear constantly in physics (transformations), computer graphics (rotations), engineering (stress analysis), and data science (linear algebra foundations).

Average Calculator goes beyond simple arithmetic mean to compute weighted mean, median, geometric mean, and harmonic mean. Different averaging methods serve different purposes: geometric mean for growth rates and financial returns, harmonic mean for rates and ratios, weighted mean for GPA calculations and grading systems. Understanding which average to use prevents common statistical mistakes.

Expected Value Calculator computes E[X], variance, and standard deviation from discrete probability distributions. Essential for probability theory courses, gambling analysis, investment risk assessment, and decision theory. Enter outcomes and their probabilities to see the long-run average result and measure of uncertainty.

Linear Regression Calculator finds the best-fit line through data points by computing slope, intercept, R² (coefficient of determination), and Pearson correlation coefficient. Scientists, researchers, and data analysts use regression to identify trends, make predictions, and quantify relationships between variables. The R² value indicates how well the line fits the data.

Scatter Plot Calculator transforms raw X,Y data pairs into visual SVG plots with axes, grid lines, and optional best-fit line overlay. Data visualization reveals patterns, clusters, and outliers that raw numbers cannot show. Download plots as SVG files for inclusion in research papers, presentations, and reports.
