im not inclined to say its (2/3)*4, that is how you read the equation, multiplication and division are equal so you do the equation from left to right in a situation with both. its order of operations.

how is the equation faulty, its an equation. there has to be a definitive school of thought and consensus on this but the equation isnt faulty. most people actuayll accept the answer as 2.

"The general consensus among math people is that "multiplication by juxtaposition" (that is, multiplying by just putting things next to each other, rather than using the "×" sign) indicates that the juxtaposed values must be multiplied together before processing other operations"
