    So 1/2x is universally interpreted as 1/(2x), and not (1/2)x, which would be x/2.

    Sorry but both my phone calculator and TI-84 calculate 1/2X to be the same thing as X/2. It’s simply evaluating the equation left to right since multiplication and division have equal priorities.

    X = 5

    Y = 1/2X => (1/2) * X => X/2

    Y = 2.5

    If you want to see Y = 0.1 you must explicitly add parentheses around the 2X.

    Before this thread I have never heard of implicit operations having higher priority than explicit operations, which honestly sounds like 100% bogus anyway.

    You are saying that an implied operation has higher priority than one which I am defining as part of the equation with an operator? Bogus. I don’t buy it. Seriously when was this decided?

    I am no mathematics expert, but I have taken up to calc 2 and differential equations and never heard this “rule” before.



  • They likely used better equipment. I’ve done the same and a black co-worker explained that black hair is much coarser than white hair so they must use much sharper shears and keep them in top shape. Your typical (white) barber shop would use shears well past when they are too dull to cut black hair in an acceptable way but work well enough for the average white customer, but sharp shears leave hair much healthier and give a cleaner cut.
