Answer:

0.000456 = 4.56 × 10-4

There must be only one digit to the left of the decimal place, so an answer like 45.6 × 10-5 is not in the correct format.


Negative Values

The notation for a negative number has a negative sign in front of the first digit:

-1.38502 × 1003 = -(1.38502 × 1003) = -1385.02

The notation for a small negative number has two negative signs: one to negate the entire number and one (in the exponent) to shift the decimal point left:

-1.38502 × 10-3 = -(1.38502 × 10-3) = -0.00138502
