Scott simplified the expression below and got 3 simplified The expression and determine Scott mistake 81 - 54 / 3 + 2
Answers
GPT-4o mini
Let's simplify the expression step by step. The original expression is:
\[ 81 - 54 / 3 + 2 \]
According to the order of operations (PEMDAS/BODMAS), we handle division and multiplication before addition and subtraction.
1. **Division**: First, we perform the division \( 54 / 3 \):
\[
54 / 3 = 18
\]
2. **Substitute back into the expression**:
\[
81 - 18 + 2
\]
3. **Now perform the subtraction and addition from left to right**:
- First, perform the subtraction:
\[
81 - 18 = 63
\]
- Then, perform the addition:
\[
63 + 2 = 65
\]
Thus, the simplified result of the expression \( 81 - 54 / 3 + 2 \) is **65**.
### Scott's Mistake
Scott stated that his simplified expression resulted in **3**. It's likely he made a mistake in the order of operations, perhaps by incorrectly adding \( 2 \) first or miscalculating the division or subtraction. The correct final answer should be **65**.
