Study the following problem on SCIENTIFIC NOTATION, rounded off to 3 significant digits.
.0005966 = _________
Solution:
Converting a decimal number to SCIENTIFIC NOTATION (a
number between 1 and 10 times a power of ten) is done by

original number to a new position which will be immediately
following the first significant digit, giving you a NEGATIVE
power of 10.
NOTE:
Count the number of places you moved the decimal point to
