Published: 26.05.2021  Elementary mathematics consists of mathematics topics frequently taught at the primary or secondary school levels. These six strands are the focus of Mathematics education from grade 1 through grade 8. In secondary school, the main topics in elementary mathematics from grade nine until grade ten are: Number Sense and algebra, Linear Relations, Measurement and Geometry.

Number Sense is an understanding of numbers and operations. In the number sense and numeration strand students develop an understanding of numbers by being taught various ways of representing numbers, as well as the relationships among numbers. Properties of the natural numbers such as divisibility and the distribution of prime numbers , are studied in basic number theory , another part of elementary mathematics.

To have a strong foundation in mathematics and to be able to succeed in the other strands students need to have a fundamental understanding of number sense and numeration. Measurement skills and concepts or spatial sense are directly related to the world in which students live.

Many of the concepts that students are taught in this strand are also used in other subjects such as science, social studies, and physical education  In the measurement strand students learn about the measurable attributes of objects, in addition to the basic metric system.

The measurement strand consists of multiple forms of measurement as Marian Small states " Measurement is the process of assigning a qualitative or quantitative description of size to an object based on a particular attribute. A formula is an entity constructed using the symbols and formation rules of a given logical language. Although written in the form of proposition , an equation is not a statement that is either true or false, but a problem consisting of finding the values, called solutions , that, when substituted for the unknowns, yield equal values of the expressions A and B.

Data is a set of values of qualitative or quantitative variables ; restated, pieces of data are individual pieces of information. Data in computing or data processing is represented in a structure that is often tabular represented by rows and columns , a tree a set of nodes with parent - children relationship , or a graph a set of connected nodes. Data is typically the result of measurements and can be visualized using graphs or images. Data as an abstract concept can be viewed as the lowest level of abstraction , from which information and then knowledge are derived.

Two-dimensional geometry is a branch of mathematics concerned with questions of shape, size, and relative position of two-dimensional figures.

Basic topics in elementary mathematics include polygons, circles, perimeter and area. A polygon that is bounded by a finite chain of straight line segments closing in a loop to form a closed chain or circuit.

These segments are called its edges or sides , and the points where two edges meet are the polygon's vertices singular: vertex or corners. The interior of the polygon is sometimes called its body. An n -gon is a polygon with n sides. A polygon is a 2-dimensional example of the more general polytope in any number of dimensions.

A circle is a simple shape of two-dimensional geometry that is the set of all points in a plane that are at a given distance from a given point, the center. The distance between any of the points and the center is called the radius.

It can also be defined as the locus of a point equidistant from a fixed point. A perimeter is a path that surrounds a two-dimensional shape. The term may be used either for the path or its length - it can be thought of as the length of the outline of a shape. The perimeter of a circle or ellipse is called its circumference. Area is the quantity that expresses the extent of a two-dimensional figure or shape.

There are several well-known formulas for the areas of simple shapes such as triangles , rectangles , and circles. Two quantities are proportional if a change in one is always accompanied by a change in the other, and if the changes are always related by use of a constant multiplier.

The constant is called the coefficient of proportionality or proportionality constant. Analytic geometry is the study of geometry using a coordinate system. This contrasts with synthetic geometry. Usually the Cartesian coordinate system is applied to manipulate equations for planes , straight lines , and squares , often in two and sometimes in three dimensions.

Geometrically, one studies the Euclidean plane 2 dimensions and Euclidean space 3 dimensions. As taught in school books, analytic geometry can be explained more simply: it is concerned with defining and representing geometrical shapes in a numerical way and extracting numerical information from shapes' numerical definitions and representations.

A negative number is a real number that is less than zero. Such numbers are often used to represent the amount of a loss or absence. For example, a debt that is owed may be thought of as a negative asset, or a decrease in some quantity may be thought of as a negative increase. Negative numbers are used to describe values on a scale that goes below zero, such as the Celsius and Fahrenheit scales for temperature.

Exponentiation is a mathematical operation , written as b n , involving two numbers, the base b and the exponent or power n. When n is a natural number i. Roots are the opposite of exponents. That is,. A root of degree 2 is called a square root and a root of degree 3, a cube root. Roots of higher degree are referred to by using ordinal numbers, as in fourth root , twentieth root , etc. Compass-and-straightedge, also known as ruler-and-compass construction, is the construction of lengths, angles , and other geometric figures using only an idealized ruler and compass.

The idealized ruler, known as a straightedge , is assumed to be infinite in length, and has no markings on it and only one edge. The compass is assumed to collapse when lifted from the page, so may not be directly used to transfer distances.

This is an unimportant restriction since, using a multi-step procedure, a distance can be transferred even with collapsing compass, see compass equivalence theorem. More formally, the only permissible constructions are those granted by Euclid 's first three postulates. Two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.

This means that either object can be repositioned and reflected but not resized so as to coincide precisely with the other object. So two distinct plane figures on a piece of paper are congruent if we can cut them out and then match them up completely. Turning the paper over is permitted. Two geometrical objects are called similar if they both have the same shape , or one has the same shape as the mirror image of the other.

More precisely, one can be obtained from the other by uniformly scaling enlarging or shrinking , possibly with additional translation , rotation and reflection. This means that either object can be rescaled, repositioned, and reflected, so as to coincide precisely with the other object. If two objects are similar, each is congruent to the result of a uniform scaling of the other. Solid geometry was the traditional name for the geometry of three-dimensional Euclidean space.

Stereometry deals with the measurements of volumes of various solid figures three-dimensional figures including pyramids , cylinders , cones , truncated cones , spheres , and prisms. A pattern is a discernible regularity in the world or in a manmade design. As such, the elements of a pattern repeat in a predictable manner. A geometric pattern is a kind of pattern formed of geometric shapes and typically repeating like a wallpaper. A relation on a set A is a collection of ordered pairs of elements of A.

Common relations include divisibility between two numbers and inequalities. A function  is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. An example is the function that relates each real number x to its square x 2. The output of a function f corresponding to an input x is denoted by f x read " f of x ". The input variable s are sometimes referred to as the argument s of the function. The slope of a line is a number that describes both the direction and the steepness of the line.

Trigonometry is a branch of mathematics that studies relationships involving lengths and angles of triangles.

The field emerged during the 3rd century BC from applications of geometry to astronomical studies. In the United States , there has been considerable concern about the low level of elementary mathematics skills on the part of many students, as compared to students in other developed countries.

Беккеру удалось увернуться в последнее мгновение. Убийца шагнул к. Беккер поднялся над безжизненным телом девушки.

Мидж смотрела на цифры, не веря своим глазам. - Этот файл, тот, что загрузили вчера вечером… - Ну. - Шифр еще не вскрыт. Время ввода - двадцать три тридцать семь и восемь секунд, однако время завершения дешифровки не указано.

Никогда о таком не слышал. Беккер заглянул в справочник Управления общей бухгалтерской отчетности США, но не нашел в нем ничего похожего.

Тело Грега Хейла растворилось в темноте, и Сьюзан, инстинктивно поджав ноги, прикрылась пиджаком Стратмора. В шифровалке никогда еще не было так тихо, здесь всегда слышался гул генераторов. Теперь все умолкло, так что можно было различить облегченный вздох раненого чудовища - ТРАНСТЕКСТА, постепенно стихающее шипение и посвистывание, сопутствующие медленному охлаждению. Сьюзан закрыла глаза и начала молиться за Дэвида. Ее молитва была проста: она просила Бога защитить любимого человека.

Мидж не поддалась. - Прими аспирин.
