Simplify. $9 + (45 \div 9) - 8 \times (-4)$
Simplify Mathematical Expression
To simplify the expression $9 + (45 \div 9) - 8 \times (-4)$, we follow the order of operations (PEMDAS/BODMAS): Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
Order of Operations Steps
-
Parentheses/Division: First, calculate the division inside the parentheses.
$45 \div 9 = 5$
The expression becomes: $9 + 5 - 8 \times (-4)$. -
Multiplication: Next, perform the multiplication.
$8 \times (-4) = -32$
The expression is now: $9 + 5 - (-32)$. -
Subtraction/Addition: Simplify the subtraction of a negative number and perform addition from left to right.
$9 + 5 - (-32) = 9 + 5 + 32$
$9 + 5 = 14$ $14 + 32 = 46$
The simplified value of the expression is 46.
