Algebraic Expression
A combination of numbers, variables, and operational symbols like addition and subtraction without an equals sign.
Equation
A mathematical statement that shows two expressions are equal, always containing an equals sign (=).
Linear Equation
An equation where the highest power of the variable is 1, meaning it has only one solution.
Variable
An unknown quantity represented by an alphabet letter like x, y, or z whose value can change.
Transposition
The method of moving a term from one side of an equation to the other while changing its mathematical sign.

Board Exam Info
In ICSE Class 6 Mathematics, this chapter typically carries around 6 to 10 marks in the final examinations. Common question types include solving linear equations for a given variable, checking whether a given value is the solution of an equation, and converting real-life word problems into equations and solving them.
Frequently Asked Questions
What is the difference between an expression and an equation?
An expression does not have an equals sign, while an equation always has an equals sign balancing two expressions.
Why do we change the sign when moving a number to the other side?
Changing the sign maintains the balance of the equation, which is equivalent to performing the same operation on both sides.
How do I check if my answer is correct?
Substitute your calculated value of the variable back into the original equation; if the left-hand side equals the right-hand side, your answer is correct.
