What is an Equation Definition: An equation is a mathematical statement with an ‘equality’ sign between two algebraic expression. The equality sign shows that the value of the expression to the left of the side (LHS or left hand side) is equal to the value of the expression to the right hand side (RHS or […]

The second place to right of the decimal point is got by dividing the number by 100 and it is known as […]
Read More →Place Value and Face Value Face Value Definition The face value means the value of the digit itself in any number. Example: In number 23, face value of 2 is 2 and 3 is 3. In 321, the place value of 3 is 3 x 100 = 300. 94652, the face value of 9 is […]
Read More →Tenths Place – Definition – Example Definition The first digit to the right of the decimal point represents the tenths place. The number after the decimal is called the decimal part and the number before the decimal point is called the whole or integral part. First we take a plane sheet which represents one whole. […]
Read More →Introduction – Pie Chart Here we will discuss in brief about construction of a Pie Chart or Pie Graph from given data. Let us see what is a pie chart or pie graph. A “pie graph or (pie chart)” is a circular chart divided into sectors, each sector represents a proportionate part of a whole. […]

In expanded form of decimal numbers we see that, how to read and write the decimal numbers. Expanded form means writing each digit in its given place value and add them all together. Expanded form of any number with […]
