Huh - didn't even know that one existed ... looks a bit like 3*Sqrt[42] ...

I know for the most part that's the method they use to teach long division in Primary School here.

That's weird - I mean, the graphic format is similar to the conventional notation for long division, but the notation goes against the common reading direction, and it doesn't conform to the equation format :? Feels wrong somehow.
Do kids learn better that way?
(And I never understood the need for mnemonics - it's just math, it is its own language, much like music. Why mix it with weird mnemonics about smelly dead animals? Gives all kinds of distracting associations)
pwhodges:
The graphic is not displaying equivalent notations; there is a clear difference between writing a division relationship in text or a formula (which may be one or two dimensional), and a layout convention for conveniently performing a tedious calculation. Bottom left is the second of those, and the others are the first. I can't imagine that anyone has ever suggested bottom left to be used like the others.
Is it cold in here?:
Today I learned that "Cathar" and "cathartic" have the same Greek root.

Today (wee hours of the morning) I learned to not waste time and effort to get equipment to pass when your standard is effed up and off by your acceptance limits.
Don't trust and always verify.

I was just wondering how pineapples reproduce, because they don't have seeds, and I'm pretty sure they haven't been cultivated to grow a seedless variety like bananas and grapes. Apparently, unpollinated pineapple plants still grow fruits, and the pineapples we eat are all unpollinated. Pollinated plants will grow seedy pineapples, which are less desirable for obvious reasons. Hummingbirds are prohibited in Hawaii as they would ruin the pineapple harvest by pollinating all the plants.
I'm not sure why a pineapple plant would spend all that energy on producing a fruit that has no seeds and cannot reproduce. Or can it...? The other thing I learned is that pineapple plants are really easy to grow yourself! All you need to do is cut off the crown and stick it in a pot. Needs very little water and a little plant food. It'll grow easily, even in non-tropical climates, and then you can look forward to harvesting your very own pineapple... in about two years. Okay, it's not quick, but it seems like a fun thing to try out. It can hardly be more disappointing than the time I grew an avocado plant...
