Concise Selina Solutions for Class 6 maths Chapter 4 Place Value


Place value is one of the fundamental concepts in mathematics. It is essential as it helps students to understand the meaning of a number. Place value is needed to understand the order of numbers as well. The concept that numbers can be broken apart and put back together gives the student a better understanding of how different mathematical operations work. It will be easy for the student to carry out operations such as addition, subtraction, multiplication, division, expanded notation, etc. Place value is the basis of our entire number system. A place-value system is one in which the position of a digit in a number determines its value. In the standard system, called base ten, each place represents ten times the value of the place to its right. Place value is needed to understand the order of numbers as well. For example, the 5 in 350 represents 5 tens, or 50; however, the 5 in 5,006 represents 5 thousand, or 5,000.
