Are actually both correct.
8*7/7*8 can be correctly interpreted as both 64 and 1. Just depends on if you consider it an in-line division symbol or 8*7 OVER 7*8
I am guessing you are early 40s/late 30s? There was a brief time where the order of operations was taught improperly in many areas.
The standing rule is PEDMAS Left to right, and the intent must be explicit brackets and parenthesis.
True, but the / isn't really a mathematical symbol .. so it's still open to interpretation.

in this instance you go from left to right.(( 8*7) / 7)* 8
if you have multiplication and division you go from left to right... same with addition and subtraction.
Generally true, but the / symbol is mathematically ambiguous:
Similarly, there can be ambiguity in the use of the slash ('/') symbol... For example, the manuscript submission instructions for the Physical Review journals state that multiplication is of higher precedence than division with a slash.

well, I love you if you are right, because if you are, then it means I'm not stupid and don't have to rely entirely on my looks to get by. :flowerforyou:0 -

I am actually surprised that no one treated it as:

____________
7*8-4+4(9^(18-5))

Also valid. There are interpretations and implementations that say divide everything to the left of the slash by everything to the right of the slash.0 -

/ isn't an arithmetic symbol. it's a representation of either a division sign or a fraction on computers.

Technically a division sign and a fraction sign are the same. One-half = 1 divided by 2 = 50% = 0.510,167,463,313,313

I mean I can go to France and demand that the police speak to me in Chinese but that would not make sense. We are on computers so we speak that language
Also, the Gatekeeper was nice for speaking English and not the demon language, because they possessed an English speaking host. Which is like speaking calculator while possessing a computer.0 -

Well following order of operations, i.e., PEMDAS, parentheses outrank exponents, which outrank multiplication and division (but multiplication and division are at the same rank), and these two outrank addition and subtraction (which are together on the bottom rank). When you have a bunch of operations of the same rank, you just operate from left to right.

Therefore it follows that you would operate the middle as ((8*7)/7)*80
