... Many civilizations over the centuries have observed that the ratio of the circumference to the diameter of a circle is constant. For example, the Romans observed that the number of paces around the outer portion of their circular temples was about three times the number of paces through the center. ...

COUNTING - Wildstrom Home Page
... If we have n numbered objects and n numbered positions for these objects, there is exactly one (and only one) way for each object to go into its correct position. There are a lot of ways for some of the objects to be correctly placed and some others to be out of place. But a more interesting questio ...

... No definite pattern emerged from that analysis and on top of all trees the simplest expression found was Mp/Mn ≈ cos(/60), valid to 5 digits. That value is elegant and simple but unique among candidates and not precise enough, the difference with the real value is more than 10,000 times the standar ...

... • Exercise: Let T be a rooted binary tree, where each internal node in the tree has two children and every node (except the root) in T has a parent. Each leaf in the tree is assigned a letter in ={A, C, G, T}. Figure 1 gives an example. Consider an edge e in T. Assume that every end of e is assign ...

... It's time to take two numbers, And add and rearrange. If you switch the adding order The answer will not change. 1+2 is 3. 2+1 is 3. Change around the numbers that you see. The sum will always equal 3! Either way you add them, The answer's still the same 1+2 is 2+1. Let's all play the Turnaround Gam ...

Addition
Addition (often signified by the plus symbol ""+"") is one of the four elementary, mathematical operations of arithmetic, with the others being subtraction, multiplication and division.The addition of two whole numbers is the total amount of those quantities combined. For example, in the picture on the right, there is a combination of three apples and two apples together; making a total of 5 apples. This observation is equivalent to the mathematical expression ""3 + 2 = 5"" i.e., ""3 add 2 is equal to 5"".Besides counting fruits, addition can also represent combining other physical objects. Using systematic generalizations, addition can also be defined on more abstract quantities, such as integers, rational numbers, real numbers and complex numbers and other abstract objects such as vectors and matrices.In arithmetic, rules for addition involving fractions and negative numbers have been devised amongst others. In algebra, addition is studied more abstractly.Addition has several important properties. It is commutative, meaning that order does not matter, and it is associative, meaning that when one adds more than two numbers, the order in which addition is performed does not matter (see Summation). Repeated addition of 1 is the same as counting; addition of 0 does not change a number. Addition also obeys predictable rules concerning related operations such as subtraction and multiplication.Performing addition is one of the simplest numerical tasks. Addition of very small numbers is accessible to toddlers; the most basic task, 1 + 1, can be performed by infants as young as five months and even some non-human animals. In primary education, students are taught to add numbers in the decimal system, starting with single digits and progressively tackling more difficult problems. Mechanical aids range from the ancient abacus to the modern computer, where research on the most efficient implementations of addition continues to this day.
