The median of a group of data refers to the middle-most figure in the group. It also refers to the figure that is halfway in the set. You would need to arrange your data from smallest to largest in order to find the median. Unlike a list of data, grouped data does not have individual values and calculating...

In the beginning of every basic mathematics book you will find three fundamental properties of numbers. These properties are: the Distributive property, the Associative property and the Commutative property. We usually ignore them. But actually these properties are so important that there are many mathematical...

The height of a triangle can be found in different ways, depending on the type of triangle and the information that is measured. Rectangular triangles, which include an angle of 90 degrees, are easiest to measure using the Pythagorean theorem (if the lengths of both sides are known) or the area formula...

Doing decimal divisions without a calculator may seem difficult, but there is an easy method which we are going to show you. The trick is simply to remove the decimal point in the division and then replace the decimal point when you get to the answer.
Although it may seem very complicated at first glance,...

An improper fraction has a top number (or numerator) which is larger than the bottom number (or denominator). Fractions typically represent parts of a whole, but improper fractions represent an amount greater than the whole. This can be misleading and needs further explanation. In this OneHowTo article...

A cube is a congruent solid with six square faces, all with equal length dimensions. The volume of a cube is measured in cubic units. Think of the dice, or any other similar object, of any size. The volume refers to the amount of space occupied and if you know the dimensions of one side of the cube,...

An oval is a geometric shape that looks like an elongated circle. Another name for an oval is an 'ellipse'. You might be asked to recognize an oval shape in primary school, secondary school and at university. The area of an oval is the amount of space contained within it. You can calculate the area...

The diameter of a circle is always a constant, no matter the size. It's the measurement of a straight line that connects two points on the circle and travels through the centre as well. The diameter determines the circumference of the circle. Although the area of a circle is generally calculated by the radius,...

Many scientific disciplines incorporate the concepts of wave frequencies and periods. Physicists, engineers and astronomers, study and work with the energy of the waves. Examples of wave energy are light waves of a distant galaxy, radio waves received by a cell phone and the sound waves of an orchestra....

The capacity to calculate and convert time units, is a useful and practical skill. For example, you can calculate your monthly income, if you know your daily wage, or you can measure productivity by calculating how many times a day or a month a task is performed. You can also convert a large number of...

If you want to know measurements of an object in cubic meters, it's possible you may want to know how much space is needed to store such object. For example, if you want to know how tall is a container, how tall the height of a building is or even the height of a truck. Cubic meters are volume measurements...
