Writing A Number in Engineering Notation Shift the

Writing A Number in Engineering Notation • Shift the decimal point in “groups of three” until the number before the decimal point is between 0 and 999. • Multiply by a power of 10 that is equal to the number of places the decimal point has been moved. • The power of 10 is positive if the decimal point is moved to the left and negative if the decimal point is moved to the right. 1
