What are the 4 basic rules of algebra?
Algebraic operations and equation solving are governed by four fundamental arithmetic and relational rules that maintain mathematical balance across expressions. The first rule is the addition property of equality, which states that adding the same quantity to both sides of an equation keeps it balanced. The second rule is the subtraction property of equality, indicating that subtracting the same value from both sides preserves equality. The third rule is the multiplication property of equality, which permits multiplying both sides by a non-zero number without altering the solution. The fourth rule is the division property of equality, allowing both sides of an equation to be divided by the same non-zero value to isolate variables correctly.
