Operations on positive and negative numbers
Operations on positive and negative numbers Mathematical rules for dealing with operations involving positive and negative numbers. Addition (+) Positive + Positive = Positive 7 + 3 = 10 Negative + Negative = Negative – 7 + (-3) = – 10 Positive + Negative(use the larger number and […]
Surface area
Surface area Surface area is total area of the surface of a three-dimensional object measured in square units. https://en.wikipedia.org/wiki/File:Area_conversion_-_square_mm_in_a_square_cm.png Metric Units – Area 1 square metre = 10 000 square centimetres, cm2 1 hectare = 10 000 square metres, m2 1 square kilometre = 100 hectares, ha 1 square metre = 100 square decimetre, dm2 […]
Temperature
Temperature Temperature is a measurement of how hot or cold something is.Temperature is measured with a thermometer and temperature is measured in degrees. Two common temperature scales are: Celsius scale (ºC) Fahrenheit scale (ºF) Celsius scale (ºC) Fahrenheit scale (ºF) 0ºC – freezing point of water 100ºC – boiling point of water 37ºC – human body temperature […]
Vertical angles, vertically opposite angles
Vertical angles, vertically opposite angles Vertical angles are the angles that lie opposite to each other when two lines intersect. Two vertical angles always share a common vertex. However, they never share a common side (arm). «Vertical» in this case means they share the same Vertex (corner point), not the usual meaning of up-down. Example: ∠AOD and ∠BOC […]
Vertex, vertices
Vertex, vertices A vertex is a point where two straight lines or rays meet to form an angle, the edges of a solid figure meet and the corners of polygons and polyhedra are vertices. Vertices are found in angles, which are measured in degrees. Pentagon Triangular Pyramid Rectangular […]
Gráfico de barras
Gráfico de barras Un gráfico de barras es una representación gráfica de datos, cantidades o números mediante barras rectangulares de diferentes alturas o longitudes. Se utilizan para comparar y contrastar diferentes tipos de datos, frecuencias u otras medidas de distintas categorías de datos. Un gráfico de barras es un gráfico que utiliza barras horizontales o verticales para […]
Plane, plane shapes
Plane, plane shapes Plane shapes are two-dimensional geometric figures: they have length and width but they have no depth. Plane shapes exist on a flat surface, known as a plane. Here are some plane shapes examples: […]
Operations
Operations Operations of integers are all the mathematic acts that happen under defined conditions. In maths, there are 4 basic rules that can solve anything. These are Addition Operation of Integers (+) Subtraction Operation of Integers (-) Multiplication Operation of Integers (*) Division Operation of Integers (/) Addition and Subtraction are inverse operations Multiplication and […]
Trapezium, trapezoid
Trapezium, trapezoid A trapezium (UK) or a trapezoid (US) A trapezium is a quadrilateral having two parallel sides of unequal length and the other two sides are non-parallel. The parallel sides of a trapezium are called bases (AD and DC or a and b) and the non-parallel sides of a trapezium are called legs (AD and […]
