Division Definition and 486 Threads

A division is a large military unit or formation, usually consisting of between 6,000 and 25,000 soldiers.
In most armies, a division is composed of several regiments or brigades; in turn, several divisions typically make up a corps. Historically, the division has been the default combined arms unit capable of independent operations. Smaller combined arms units, such as the American regimental combat team (RCT) during World War II, were used when conditions favored them. In recent times, modern Western militaries have begun adopting the smaller brigade combat team (similar to the RCT) as the default combined arms unit, with the division they belong to being less important.
While the focus of this article is on army divisions, in naval usage, "division" has a completely different meaning, referring to either an administrative/functional sub-unit of a department (e.g., fire control division of the weapons department) aboard naval and coast guard ships, shore commands, and in naval aviation units (including navy, marine corps, and coast guard aviation), to a sub-unit of several ships within a flotilla or squadron, or to two or three sections of aircraft operating under a designated division leader. Some languages, like Russian, Serbian, Croatian and Polish, also use a similar word, divizion/divizijun/dywizjon, for a battalion-size artillery or cavalry unit.

    B Remainder when the dividend is less than the divisor

    I am Sorry it's a silly question but its been bothering me, So I needed to ask... In the process of division, when there is a condition like- 4/5 when the divisor is greater then the dividend. why is the Remainder 4 ? as when the divisor is greater then the dividend then the division goes in...

    B Why are the division rules for surds the way they are?

    Why does, 4√64÷2√4 =2√16 ? I can see the method (4÷2=2, √64÷√4=√16) But why is it not; 4 times √64 divided by 2 times √4 (as per BODMAS) i.e, 4 times 8 divided by 2 times 2, which = 32 Nb. When I put it into my calculator that way it gives 32 as the answer (4*√64÷2√4)

    B 1 divided by infinity equals zero (always?)

    I understand the mathematics that 1 divided by infinity is virtually zero and so equals zero. I look on the internet and that is the answer that I get. Is this a simplification for early mathematics learning and, if I continue, will I find a more complex answer? The reason that I ask is that I...

    B Relation between Division and multiplication

    For example what is ##\frac {169}{13} = ?## This says “When ##169## is divided into ##13## groups how many there are in each group?” This can be converted into a multiplication problem like this “##13## groups of how many in each group makes ##169##?” This is ##13 * ? = 169##. It can be solved...

    B Confusion about division by zero in sets

    So the confusion here is that division by zero is often said to be undefined. So whereas, the point (0,0) certainly appears in the set of values where x=y, does the point (0,0) appear in the set of values where 1=y/x. Why or why not? In other words are the set of points where x=y the same as...

    Why does a division by zero produce an error or undefined message?

    A division by zero is a mathematical oddity, , if a computer or calculator etc performs a 1\0 they would crash, the OS prevents the execution, and displays ERROR or UNDEFINED, , , some versions of windows calculator display positive or negative infinity, , try it Any ideas on this ?

    Using Kirchhoff's laws on this current division problem
