When a number between 0 and 1 is written in scientific notation, the exponent will always be negative. This is because the decimal point is moved to the right to convert the number into the form ( a \times 10^n ) (where ( 1 \leq a < 10 )), resulting in a negative exponent that indicates how many places the decimal was shifted. For example, the number 0.005 can be expressed as ( 5 \times 10^{-3} ).
