Solving the Equation: (8-(4-2)-(7-9)) x 9

This article will walk you through solving the equation (8-(4-2)-(7-9)) x 9 step-by-step, using the order of operations (PEMDAS/BODMAS).

Understanding the Order of Operations

Before we begin, let's remember the order of operations, often remembered by the acronym PEMDAS or BODMAS:

  • Parentheses ( Brackets)
  • Exponents ( Orders)
  • Multiplication and Division (from left to right)
  • Addition and Subtraction (from left to right)

Solving the Equation

  1. Simplify the inner parentheses:

    • (4-2) = 2
    • (7-9) = -2

  2. Substitute the simplified values:

    • (8 - 2 - (-2)) x 9

  3. Simplify further:

    • (8 - 2 + 2) x 9
    • (8) x 9

  4. Multiply:

    • 8 x 9 = 72

Therefore, the solution to the equation (8-(4-2)-(7-9)) x 9 is 72.
