Chapter: Algebra
An arithmetic or algebraic procedure is a sequence of logical steps that must be followed to arrive at a correct solution. In arithmetic, this might involve carrying out calculations in the correct order. In algebra, it might involve solving for a variable through a series of transformations. The skill here is not only in executing the procedure but also in analyzing whether the steps being used are valid and consistent with mathematical rules.
Following step-by-step procedures
In arithmetic, following a procedure usually means respecting the order of operations, often summarized as parentheses, exponents, multiplication/division, and addition/subtraction. Each step narrows the problem until the final answer is reached.
Example: Simplify 18 ÷ (3 + 3) × 2. Step 1: Inside parentheses → 3 + 3 = 6. Step 2: Division → 18 ÷ 6 = 3. Step 3: Multiplication → 3 × 2 = 6.
