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.

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 -

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

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.

AND not THEN is the rule. Left to right.
True.
Used to be that implied multiplication (ie. 2x) had higher precedence, but that's changing now too. Nowadays 2x/2x=x^2, when it used to = 1
2 * x / 2 * x
= (2x) / 2 * x
= x * x0 -

2 * x / 2 * x
= (2x) / 2 * x
= x * x
This wasn't making sense. Then i see the problem 2x = x + x.
(x + x) / (x + x) = 10 -
I don't see 2x as being 2*x because there's no parentheses around the x or a multiplication symbol between them so 2x/2x =/= x^2 because 2x = x + xAND not THEN is the rule. Left to right.

2x =/= 2*x
Wolfram Alpha changed in early 2013 to treat implied multiplication the same as explicit multiplication (formerly, implied multiplication without parentheses was assumed to bind stronger than explicit multiplication). 2x/2x, 2*x/2*x, and 2(x)/2(x) now all yield x^2. The TI 89 and TI 86 calculators also yield x^2 in all three cases.0 -
But who was clear notation?0

I'm not saying you're wrong. I just don't understand how 2x can be implied to be multiplication. I just can't wrap my own brain around it. That's like me saying, "Here's 2 3s," and someone trying to say that equals 9 because by having 2 3s, I imply that they should be multiplied. Personally, I just don't get it. :ohwell:
