Frequently Asked Questions
Algebra Fundamentals
Variables and Constants
Variables (like x, y) represent unknown values, whilst constants are fixed numbers. In the equation 2x + 5 = 13, ‘x’ is the variable, and 2, 5, and 13 are constants.
Order of Operations
Always follow BODMAS (Brackets, Orders, Division/Multiplication, Addition/Subtraction) when solving equations. This ensures accurate solutions every time.
Balancing Equations
Whatever operation you perform on one side of an equation, you must perform on the other side to maintain balance. This fundamental principle keeps equations mathematically valid.
Checking Solutions
Always substitute your answer back into the original equation to verify it’s correct. This step catches calculation errors and confirms your solution is valid.
