The result of the expression \(81 \div 9 \cdot 2 + 7 \cdot 6\) is \(60\).
Solución
Let's solve the expression step by step, following the order of operations (PEMDAS/BODMAS):
1. **Identify the expression**:
\[
81 \div 9 \cdot 2 + 7 \cdot 6
\]
2. **Step 1: Perform division and multiplication from left to right**:
- First, we divide \(81\) by \(9\):
\[
81 \div 9 = 9
\]
- Now, we multiply the result by \(2\):
\[
9 \cdot 2 = 18
\]
3. **Step 2: Calculate the multiplication \(7 \cdot 6\)**:
\[
7 \cdot 6 = 42
\]
4. **Step 3: Add the results from Step 1 and Step 2**:
\[
18 + 42 = 60
\]
Thus, the final result of the expression \(81 \div 9 \cdot 2 + 7 \cdot 6\) is \(60\).

The Deep Dive
Let's break this down step by step! First, we need to perform the division and multiplication from left to right according to the order of operations. We start by dividing 81 by 9, which gives us 9. Now we move on to the next part: \(9 \cdot 2\), which equals 18. So far, we have: \(18 + 7 \cdot 6\) Now you can tackle the multiplication of \(7 \cdot 6\), which is 42. Now we can combine our results!
