No, if you shift the decimal point to the left, the exponent of base 10 is positive. The exponent of base 10 is negative if you shift the decimal point to the right.
its 5.5 rather than 5 and a half (or 5 1/2) It means that you represent fractions of numbers in tenths (and hundredths, thousandths, etc) rather than in fractions (or in eighths or twelfths or some such). the above notation would be expected in the US. However, in Europe, the notation would be 5,5 for 5 and a half. Basically, the Europeans reverse the use of comma and period in their decimal notation.
Scientific notation gives a compact notation, which is especially useful for writing down - and doing calculations with - very large, and very small, numbers.
It is important to have the decimal place in the correct position when doing calculations manually.
3,560,000 in scientific notation is written as 3.56 x 10^6. This notation represents the number 3.56 multiplied by 10 raised to the power of 6, which is equivalent to moving the decimal point 6 places to the right to convert the number into a standard form.
