### DAV Class 4 Maths Chapter 3 Worksheet 3 Notes

Multiplication (Orally):

In order to multiply a number by 100, 200… 900 we multiply the number by 1, 2, 3…9 respectively and put two zeros on right of the product.

e.g. 3 × 1800 = 3 × 18 × 100 (3 × 18 and two = 5400

Similarly

2 × 7000 = 2 × 7 × 1,000

= 14,000
