Basic Algebra Solver

About Basic Algebra

Algebra is just arithmetic with one or two unknown values written as letters. The 14 solved examples take you from variables and constants, through simplifying expressions by combining like terms, to solving linear equations in one variable using transposition. The harder examples build a linear equation from a short word problem ("the sum of a number and 5 is 18") — that translation step is what catches students who can solve the equation but freeze when they have to write it down themselves. Each example ends with the verification step too, the one most students skip in exams.

What this calculator does

• Step-by-step working. Every intermediate line is shown, in the layout examiners reward in CBSE / ICSE and university scripts.
• Graphs where they help. Functions and equations are plotted so you can see the result rather than just read it.
• Verification. The answer is substituted back into the original problem so you know the working is consistent.
