OR calculate just how much water that dam can hold back.
Uhm - no, it’s ambiguous. The order of the evaluation can be one of two ways depending on operator precedence. We’ve gotten two possible interpretations - that ALONE should be an indication that it’s ambiguous.
If it were written correctly - parens would have been used to disambiguate the results to guarantee a single possible interpretation.
The bipartisan compromise answer is 143.
He was a great teacher. No calculator...he did allow slide rules...and this was about 1980.
48÷2(9+3)
#1 the () is the priority..
#2 next would be the other equation (48/2)..
#3 the () is multiplied times the answer of #2
#4 288
A TI calculator doing RPN - bight your tongue!
288, division trumps multiplication.
Using standard left-to-right decoding, the answer is 288.
(I had to check my memory that left-to-right is the RULE, as opposed to a preferred method, BTW)
Sixty-Nine...Hmmm...
288
100100000
PEMDAS
(Please excuse my dear Aunt Sally)= (parenthesis, exponents, multiplication, division, addition, subtaction.)This is the correct order of operations.

Okay...How many of you have slept with your calculator??
How many have used it as the "remote" to change the channel?
Did you get that number off a wall?
I got 0x120.
lol.. did you use hexeditor to get that answer? ;)
That is correct, because perenthesis supercede multiplication and division.

The answer is 2. I am 100 percent sure!!
Would that ALL our problems were this easy!!
AND people RESPECTED the RULES (constitution).
Which “sign” takes precedence? ie do you use FIRST?
The RULE says “divided by”.
That’s IT.
The answer is
2
Casio fx-115n says it’s 288. And I guess there’s no news to talk about today?
