Let's cut out the usage of the antiquated divisor symbol. That would help the human race cut back on algebraic errors.

yes. i think the only reason the symbol is known nowadays is because of modern calculators actually. i don't think you'll find it much at all in math literature before mechanical adding machines/cash registers became widespread.

It's not that confusing, you just break the equation down into components, in this case '10' and '2x'.

The argument that '2x' is an 'implied multiplication' is fucking stupid because by the same logic '10' is an implied power.

Mathfags couldn't be bothered writing shit on the board over and over so they turned everything into a soup of one letter variables and "oh let's just not write the sign it'll be faster". This ruined math forever, but it is too late to fix it. The only choice is to remember whatever random bullshit rules apply in every situation and hope everyone gets them right.

Obelus always implies division between the left and the right side, therefore 5/x and the answer to the other thread is 1. Everybody who answered differently is a cretin

2÷1×3
so by your logic that equals 2/3?
and what about 2÷3÷5? which is the left and which is the right?

You might want to think before you post things next time, it's literally primitive. Left and right side are of course defined for each obelus symbol, why do you think there is any sort of ambiguity?

2÷3÷5 = (2÷3)÷5 = 2÷(3÷5) = 2/3/5 = 10/3

Are you still confused?

It doesn't apply any longer. It now works the same as the multiplication symbol, applying only to the two factors directly to the left and right. Use parenthesis if you want to a certain section to be the divisor.

>>10851876
This. Once you start explicitly writing in your multiplication symbols then there is no ambiguity like this bullshit. Writing a dot doesn't even take that long.
