Study the following problem on SCIENTIFIC NOTATION, rounded off to 3 significant digits.

636.42 = ___________________________

Solution:

Converting a whole number to SCIENTIFIC NOTATION (a

number between 1 and 10 times a power of ten) is done by

moving the decimal point LEFT from its position in the

original number to a new position which will be immediately

following the first significant digit, giving you a POSITIVE

power of 10.

NOTE:

Count the number of places you moved the decimal point to

the LEFT in the original number to its new position following

the first significant number. This will give you the proper

exponent for your POSITIVE power of 10.
