what does congruent mean?its for math.?

Congruent basically means the same. For math, this is probably regarding geometry. Two congruent triangles, when superimposed (placed on top of another) are exactly the same (rotation may be required).

not quite sure what exactly you mean, but i would guess\n\n2+2+2+2 or 4+4 or 1+1+1+1+1+1+1+1

This was a form of math that gained a small following several years ago with the Hmong of Thiland. It's not used very much today due to its limited application.   Edited comment:  Pastor Dave is correct, it's still used. I think it was also used for a few months at Enron, Corp.

a sequence of numbers in which the two previous numbers add to give you the third.\n1,1,2,3,5,8,13...ect\nOne plus one is two.\nOne plus two is three\nTwo plus three is five\nFive plus three is Eight...\n\nIt 's being found increasingly in nature now as well.

marque,\n\nIt was a joke Euler pulled to put down some guy who was ingnorant of mathematics who was causing a problem. This link tells the story. It's a bit humorous but doesn't really mean anything. You'll have to scroll down a bit but the whole thing is good\n\nhttp://scidiv.bcc.ctc.edu/Math/Euler.html

It means "to the power of". Used for indices \n\neg. 4^5 is 4 to the power of 5

Actually, it should read that p divides a^(p-1) - 1\nLemma:\nIf p does not divide a, then the integers\n{ a, 2a, 3a, ... (p-1)a } \nare congruent mod p (in some order) to the numbers\n{ 1, 2, 3, ... , p-1 }\n[Proof by contradiction.  Assume not.  Every number is congruent to one of { 0, 1, 2, 3, ... , p-1 }(mod p), but since p does not divide a then no member in the first set is congruent to 0. Then some xa, ya (x,y<p) in the first set would have to be congruent to the same number in the second set and therefore to each other (mod p).  But that would mean that p divides xa-ya=a(x-y), and since p doesnt divide a, and p certainly cannot divide x-y<p, this leads to a contradiction]\n\nSince the two sets are congruent, their products are congruent, so\n(a)(2a)(3a)...((p-1)a) ≡ (1)(2)(3)...(p-1) (mod p)\n(a)(2a)(3a)...((p-1)a) - (1)(2)(3)...(p-1) ≡ 0 (mod p)\n(1)(2)(3)...(p-1)*[a^(p-1) - 1] ≡ 0 (mod p)\nwhich means p divides (1)(2)(3)...(p-1)*[a^(p-1) - 1]\nSince p cannot divide (1)(2)(3)...(p-1),\np must divide a^(p-1) - 1.\n\n\nakash that is not correct, since you cant choose a=10 and p=5 since 5 divides 10.  you must choose p and a such that p does not divide a.

We use the symbol above the number 6 on the keyboard to show exponents.  For example, 2 squared is typed 2^2 = 4.\n\nWhy don't you use the symbol ^ and retype your question correctly?\n\nGuido

In math, it means "can be divided" by numbers other than themselves (3 is divisible but only by 1 and itself). Prime numbers like 1, 3, 5, 7, 11, 13, 17, etc. are unique in that you can't divide them by another number to end up with another whole number. Non-prime numbers, like 4, 6, 8, 9, 10, 12, 14 and 16 are divisible because you can divide them by other numbers like 2, 3 or 4 and end up with another whole number (no decimals). Surely, some mathematician will explain this better and in more correct terms, but I did what I could on such short notice.

1. It's one multiplied by ten to the twenty-third power.\n  -Otherwise ten to the twenty-third power.\n\n2. It is also an example of multiplicative identity.\n\nSorry if that is not what you are looking for.

It's the symbol for factorial.  It means multiply the number n by n-1, then by n-2, etc. until you get to 1, e.g., 5! = 5*4*3*2*1.  Also, 0! is defined as 1.

fraction [Lat.,=breaking], in arithmetic, an expression representing a part, or several equal parts, of a unit.\nNotation for Fractions\n\nIn writing a fraction, e.g., 2/5 or 2/5, the number after or below the bar represents the total number of parts into which the unit has been divided. This number is called the denominator. The number before or above the bar, the numerator, denotes how many of the equal parts of the unit have been taken. The expression 2/5, then, represents the fact that two of the five parts of the unit or quantity have been taken. The present notation for fractions is of Hindu origin, but some types of fractions were used by the Egyptians before 1600 B.C. Another way of representing fractions is by decimal notation (see decimal system).\n\nCharacteristics of Fractions\n\nWhen the numerator is less than the denominator, the fraction is proper, i.e., less than unity. When the reverse is true, e.g., 5/2, the fraction is improper, i.e., greater than unity. When a fraction is written with a whole number, e.g., 31/2, the expression is called a mixed number. This may also be written as an improper fraction, as 7/2, since three is equal to six halves, and by adding the one half, the total becomes seven halves, or 7/2. A fraction has been reduced to its lowest terms when the numerator and denominator are not divisible by any common divisor except 1, e.g., when 4/6 is reduced to 2/3.

It means the person saying that sentence is not good in Mathematics. You are correct, Math is shortened version for Mathematics.

the order of any element, modulo p, divides p-1 (which is an even number for everything except the stupid case of p=2, which i'm omitting) and every number relatively prime to p, raised to the (p-1) power will be congruent to 1 (modulo p)\n\ntherefore b^(p-1) = 1 (mod p)\nso a^((p-1)/2) = (b^2)^((p-1)/2) = b^(p-1) = 1 (mod p)\ntherefore order(a) divides ((p-1)/2) and hence order(a) does not equal (p-1), which is the requirement for being a primitive root.\n\nhence, a can never be a primitive root
