Thinking...
Okay, let's see. I need to solve this math problem: (17 multiplied by 23) p
plus (144 divided by 12) minus 89. Alright, let me break it down step by st
step. First, I remember that according to the order of operations, I should
should handle the multiplication and division before addition and
subtraction. So, let me start with the multiplication part, which is 17
times 23. Hmm, 17 times 20 is 340, and 17 times 3 is 51. Adding those
together, 340 + 51 equals 391. Wait, let me check that again. 17*20 is 340,
340, and 17*3 is indeed 51. So 340 + 51 is 391. Okay, that seems right.
Next, there's the division part: 144 divided by 12. Let me think. 12 times
12 is 144, so 144 divided by 12 should be 12. Yeah, that's straightforward.
straightforward. So that part is 12.
Now, putting those results back into the original equation, it becomes 391
plus 12 minus 89. Let me write that out: 391 + 12 = 403. Then, 403 minus 89
89. Hmm, subtracting 89 from 403. Let me do that step by step. 403 minus 80
80 is 323, and then minus 9 more is 314. Wait, let me verify that.
Alternatively, 403 - 89. Maybe another way: 403 - 90 would be 313, but
since it's 89, that's 313 + 1 = 314. Yeah, that seems correct. So the final
final result should be 314. Let me just recap all the steps to make sure I
didn't make any mistakes.
First, 17*23: 17*20=340, 17*3=51, 340+51=391. Then 144/12=12. Then adding 3
391+12=403. Subtracting 89 from 403 gives 314. Seems all right. Wait, but l
let me check the multiplication again because sometimes I might
miscalculate. Let me do 17*23 another way. 23 can be thought of as 20 + 3.
So 17*20 is 340, 17*3 is
