Thinking...
First, I need to calculate 17 multiplied by 23. Breaking it down, 10 times
23 is 230, and 7 times 23 is 161. Adding these together gives me 391.
Next, I'll divide 144 by 12. Since 12 goes into 144 twelve times with no re
remainder, the result of this division is 12.
Now, I have two numbers: 391 and 12. Subtracting 89 from these gives me 391
391 minus 89 equals 302.
...done thinking.
**Solution:**
We need to evaluate the expression:
\[
(17 \times 23) + \left(\frac{144}{12}\right) - 89
\]
Let's break it down step by step.
### Step 1: Calculate \(17 \times 23\)
\[
17 \times 23 = (10 + 7) \times 23 = 10 \times 23 + 7 \times 23 = 230 + 161
= 391
\]
### Step 2: Calculate \(\frac{144}{12}\)
\[
\frac{144}{12} = 12
\]
### Step 3: Substitute the calculated values back into the original
expression
\[
391 + 12 - 89
\]
### Step 4: Perform the addition and subtraction from left to right
First, add \(391\) and \(12\):
\[
391 + 12 = 403
\]
Next, subtract \(89\) from \(403\):
\[
403 - 89 = 314
\]
### Final Answer
\[
\boxed{314}
\]
