Question 2

anatomy of the notations

Answer 2

Coefficient, base, and power

Question 3

it is a form of powers of 10 notations in which number is expressed as a number between 1 and 10 times a power of 10

Answer 3

scientific notation

Question 4

the 3 rules of converting decimal to scientific notation

Answer 4

1. Express the number from 1-9, times a power of 10
2. If the decimal is moved to the left, then the power of 10 is positive. If the decimal is moved to the right, then the power of 10 is negative
3. the power of 10 always equals the number of places by which the decimal point has been shifted to the left or to the right from the original number

Question 5

2 rules of converting scientific to decimal notation

Answer 5

1. If the power of 10 is positive, move the decimal point to the right
2. if the power of 10 is negative, move the decimal point to the left

Question 6

it is similar to the scientific notation, except that the powers of 10 are always multiples of 3

Answer 6

Engineering notation

Question 7

3 rules of engineering notation

Answer 7

1. express the original number in scientific notation first
2. the power must either be increased or decreased until it is a multiple of 3
3. If the power is increased, the decimal point is moved to the left. If the power is decreased, the decimal point moves to the right
