    Study Notes

    Simplifying Expressions using Order of Operations

    • The expression involves various operations: addition, subtraction, division, and brackets. Order of operations (PEMDAS/BODMAS) dictates the sequence in which these operations are performed.
    • PEMDAS (Parentheses/Brackets, Exponents/Orders, Multiplication and Division from left to right, Addition and Subtraction from left to right) is a crucial rule in evaluating expressions.

    Evaluating the Expression

    • The expression is 25 - 1 / 2 { 5 + 4 - ( 3 + 2 - 1 + 3 )}
    • First step: Parentheses/Brackets. Focus on the innermost set of brackets first:
      • 3 + 2 - 1 + 3 = 7
    • Second step: Simplify the expression within the next set of brackets:
      • 5 + 4 - 7 = 2
    • Third step: The expression now is 25 - 1 / 2 {2}
    • Fourth step: Brackets again:
      • 25 - 1/4
    • Fifth step: Division:
      • 1/2 = 0.5; Now we have 25 - 0.5 * 2
      • 0.5 * 2 = 1
    • Sixth step: Subtraction:
      • 25 - 1 = 24

    Integer Arithmetic

    • The expression uses integers (positive and negative whole numbers).
    • Operations involve integer addition, subtraction, multiplication, and division. Following the order of operations (PEMDAS) is critical for accuracy.

    Bracket Notation

    • Brackets in mathematics (parentheses, curly braces, and square brackets) define an operation or grouping of values
    • Correctly using bracket notation is essential for avoiding mistakes.
    • Innermost brackets are evaluated first.

    Evaluating Expressions

    • Evaluating an expression means finding its numerical value. This requires following the rules of precedence, particularly the order of operations (PEMDAS/BODMAS).
    • Simplification procedures are necessary steps in reaching the numerical answer.

    Order of Operations

    • Order of operations is the sequence in which operations in a mathematical expression are to be performed.
    • PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right) or BODMAS (Brackets, Orders, Division and Multiplication, Addition and Subtraction), provide a universal standard.
    • Incorrect order of operations will lead to an incorrect solution.

    Final Answer

    • 25 - 1/2{5 + 4 - (3 + 2 - 1 + 3)} = 24
