To solve the expression 50+89−32×7+950 + 89 – 32 \times 7 + 9, we need to follow the order of operations, often remembered by the acronym PEMDAS:
- Parentheses
- Exponents
- Multiplication and Division (from left to right)
- Addition and Subtraction (from left to right)
Let’s break it down step by step:
Step 1: Perform the Multiplication
32×7=22432 \times 7 = 224
Step 2: Substitute Back into the Expression
50+89−224+950 + 89 – 224 + 9
Step 3: Perform Addition and Subtraction from Left to Right
- Addition:
50+89=13950 + 89 = 139
- Subtraction:
139−224=−85139 – 224 = -85
- Addition:
−85+9=−76-85 + 9 = -76
Final Result
50+89−32×7+9=−7650 + 89 – 32 \times 7 + 9 = -76
So, the final answer is −76-76.
