It is essential to understand how to form an equation from a word problem in which 'of' is used. Below is discussed the use of the word 'of' in Math along with example usages in word problems.
The word 'of', in Math, simply means multiplication. Generally, whenever you encounter this word, put a multiplication sign in your equation at that point. Use of 'of' in math in percentage and fraction problems The word 'of' is used very simply in percentage problems, and usually you just have to replace 'of' with a multiplication sign to get rid of it! Usage of the word 'of' in math in percent problems is similar to its usage in fraction problems.
Word problems illustrate a mathematical relationship between two or more variables. It is an irrational number, which means that its decimal places continue to infinity. However large a number you have, you can always have a larger one, because you can always add one to it. Infinity is not a number, but the idea of numbers going on for ever. You cannot add one to infinity, any more than you can add one to a person, or to love or hate. Pipe ' ' is also also referred to as vertical bar, vbar, pike and has many uses in mathematics, physics and computing.
When an object or point moves in a cyclic pattern, or is subject to vibration or oscillation e. See an introduction to geometry for more. The line connecting the centre of a regular polygon with one of its sides.
The line is perpendicular at a right angle to the side. Geometric area is defined as the space occupied by a flat shape or the surface of an object. Area is measured in square units, such as square metres m 2. For more, see our page on area, surface area and volume. An asymptote is a straight line or axis that is specifically related to a curved line.
As the curved line extends tends to infinity, it approaches, but never touches, its asymptote that is, the distance between the curve and the asymptote tends to zero. It occurs in geometry and trigonometry. A line of reference about which an object, point or line is drawn, rotated or measured. In a symmetrical shape, an axis is usually a line of symmetry. A coefficient is a number or quantity multiplying another quantity. It is usually placed before a variable. In the expression 6 x , 6 is the coefficient and x is the variable.
The circumference is the length of the distance around the edge of a circle. It is a type of perimeter that is unique to circular shapes.
For more, see our page on curved shapes. Data are a collection of values, information or characteristics, which are often numerical in nature. They may be collected by scientific experiment or other observational means. They may be quantitative or qualitative variables. A datum is a single value of a single variable. See our page on Types of Data for more. Diameter is a term used in geometry to define a straight line that passes through the centre of a circle or sphere, touching the circumference or surface at both ends.
The diameter is twice the radius. Extrapolate is a term used in data analysis. It refers to the extension of a graph, curve, or range of values into a range for which no data exists, inferring the values of unknown data from trends in the known data. A factor is a number that we multiply by another number. A factor divides into another number a whole number of times. Most numbers have an even number of factors.
A square number has an odd number of factors. A prime number has two factors — itself and 1. A prime factor is a factor that is a prime number.
The mean average of a set of data is calculated by adding all numbers in the data set and then dividing by the number of values in the set. When the data set is ordered from least to greatest, the median is the middle value. The mode is the number that occurs most times. The basic arithmetical operations are addition, subtraction, multiplication and division.
The order in which operations are carried out in a calculation is important. The perimeter of a 2-dimensional shape is the continuous line or the length of the line that defines the outline of the shape. The perimeter of a circular shape is specifically called its circumference.
Our page on Perimeter explains this in more detail. Proportion is a relative of ratio. Ratios compare one part to another part, and proportions compare one part to the whole. Proportion is related to fractions. It is an important rule that applies only to right-angled triangles.
Quantitative data are numeric variables or values that can be expressed numerically, i. Qualitative data are type variables that do not have a numerical value and may be expressed descriptively, i.
