What Is a Substitution Calculator?
A substitution calculator is a specialized tool or software feature designed to perform substitution in various mathematical contexts. This typically includes: 1. Evaluating algebraic expressions by substituting given values for variables (e.g., finding the value of 2x+3 when x=5). 2. Solving systems of equations using the substitution method. 3. Performing u-substitution for integrals in calculus. These calculators provide step-by-step solutions, making them invaluable for understanding the underlying process.
