Selina Concise Mathematics Class 6 ICSE Solutions – Number System Selina Concise Mathematics Class 6 ICSE Solutions – Number System(Consolidating the Sense of Numberness) IMPORTANT POINTS 1. Place-Value (Local Value) : The place value (Local-value) of a digit depends upon the position, it occupies in the number: For example : In the number 6453 the place value of 6 is 6 thousand = 6 x 1000 = 6000 the place value of 4 is 4 hundred = 4 x 100 = 400 the place value of 5 is 5 ten = 5 x 10 = 50 the place value of 3 is 3 one = 3 x 1 = 3 2. Face-Value (True-Value) : Each digit in a number has a fixed value, regardless to its position in the number For Example : In the above number 6453 Face value of 6 is 6, 4 is 4, 5 is 5 and 3 is 3 3. An Abstract Number : Which does not refer to any particular unit e.g., 3, 5, 9. 4. A Concrete Number : Which refers to particular unit e.g., 3 boys, 5 girls, 9 rooms etc. The smallest (least) one digit Number is 1. The largest (greatest) one digit number i

Selina Concise Mathematics Class 6 ICSE Solutions – Estimation Selina Concise Mathematics Class 6 ICSE Solutions – Estimation EXERCISE 2(A) Question 1. Round off each of the following to the nearest ten : (i) 62 (ii) 265 (iii) 543 (iv) 8261 (v) 6294 (vi) 3008 (vii) 72326 Solution: If the digit at ones place is less than 5, replace ones digit by 0, and keep the other digit as they are : And if the digit at ones place is 5 or more than 5, increase tens digit by 1, and replace ones digit by 0. (i) 62 – 60 (ii) 265 – 270 (iii) 543 – 540 (iv) 8261 – 8260 (v) 6294 – 6290 (vi) 3008-3010 Question 2.
