HI!.

when youmultiply(positive)powersof 10 (that is 10, 100, 1000,...) on a certain number, you just needto move the decimal point to the right. thenumber of movement is equal to the number of zeros.

example:245 x 10

you can write 245 with the decimal point right?245is also245.or245.00(etc.)

that means, since 10 has 1 zero, you will move the decimal pointonceto the right which gives you245 x 10 = 2450.example:

3.14159265 x 10001000 has 3 zeros, therefore, you will move the decimal point three times. so

3.14159265 x 1000 = 3141.59265

get it already?

fordivision, instead of moving to the right, you willmove it to the left.

example:2.1532 divide by 100since 100 has to zeros, move the decimal point twice to the left. so

2.1532 divide by 100gives you.021532

NOTE: you can always write a number byadding zerosto theright mostor to theleft mostof the number butnot in between the digitsof the number.

example:20.23is the same as20.23000000also the same as00020.23and also as00020.2300000

but it is not the same as20.002300and2000.2300..
