Solving the Equation: (6 + 23) x (32 - 25) + 7²
This article will guide you through the step-by-step solution of the equation (6 + 23) x (32 - 25) + 7².
Understanding the Order of Operations (PEMDAS/BODMAS)
Before diving into the calculations, we need to remember the order of operations. It's crucial to perform operations in the correct sequence to arrive at the correct answer. Here's a common acronym to help us remember:
PEMDAS:
- Parentheses
- Exponents
- Multiplication and Division (from left to right)
- Addition and Subtraction (from left to right)
BODMAS:
- Brackets
- Orders
- Division and Multiplication (from left to right)
- Addition and Subtraction (from left to right)
Solving the Equation:
-
Parentheses/Brackets: We start by solving the expressions inside the parentheses:
- (6 + 23) = 29
- (32 - 25) = 7
-
Exponents/Orders: Next, we calculate 7 raised to the power of 2:
- 7² = 7 x 7 = 49
-
Multiplication: Now, we multiply the results we obtained:
- 29 x 7 = 203
-
Addition: Finally, we add the last result to the result of the exponent calculation:
- 203 + 49 = 252
Final Answer
Therefore, the solution to the equation (6 + 23) x (32 - 25) + 7² is 252.
