\(72\div9-15+4\times3=?\)
Solving the Equation: $72 \div 9 - 15 + 4 \times 3$
To find the value that replaces the question mark (?) in the given equation, we need to follow the standard order of operations, often remembered by the acronym PEMDAS or BODMAS. This rule tells us the sequence in which to perform different mathematical operations:
- Parentheses (or Brackets)
- Exponents (or Orders)
- Multiplication and Division (from left to right)
- Addition and Subtraction (from left to right)
Step-by-Step Calculation
Let's break down the equation $72 \div 9 - 15 + 4 \times 3$ step-by-step:
-
Division: First, perform the division operation.
$72 \div 9 = 8$
The equation now becomes: $8 - 15 + 4 \times 3$.
-
Multiplication: Next, perform the multiplication operation.
$4 \times 3 = 12$
The equation simplifies to: $8 - 15 + 12$.
-
Subtraction: Now, perform the subtraction from left to right.
$8 - 15 = -7$
The equation becomes: $-7 + 12$.
-
Addition: Finally, perform the addition.
$-7 + 12 = 5$
Final Result Analysis
Following the order of operations (PEMDAS/BODMAS), the calculation yields 5.
Therefore, the value that comes in place of the question mark (?) is 5.
