2. perform multiplication easily;

3. develop the speed in multiplying numbers.When the factors are is in the power of ten such as 10, 100, 1000, 10 000, 100 000 and so on and so fort, just multiply the digit that is form 1 to 9 and add the number of zeros. <br />Example:<br />31 x 100 = 3 100<br />270 x 10 = 2 700<br />15 000 x 100 = 1 500 000<br />When the factors are end in both zero, multiply the significant number and used the number of zeros in both factors to the product.<br />Example:2 380 x 40 = 95 2002 380 x 400 = 952 000<br />-599090-405305WORSHEET NO. 14<br />NAME: ___________________________________DATE: _____________ <br />YEAR & SECTION: ________________________RATING: ___________<br />85725217170<br />A.Based to the power of ten, multiply the following. <br />1. 100 x 320 =_________6. 75 x 100 =_________<br />2. 10 x 27 = __________7. 56 x 10 = __________<br />3. 100 x 414 =________8. 38 x 100 =__________<br />4. 176 x 100 =________9. 68 x 10 000 =________<br />-425669023435. 39 x 1 000 = ________10. 59 x 1 000 =________<br />85725224790<br />B.Find the product of the following.<br />1. 2 080 x 30 =____________ 6. 720 x 40 =____________<br />2. 3 150 x 60 =____________7. 7 230 x 50 =___________<br />3. 1 470 x 20 =____________8. 2 030 x 60=___________<br />4. 30 x 90 =____________ 9. 456 x 70=____________<br />5. 30 x 80 =____________10. 86 x 690=____________<br />
