Frame 5-12.

small number, one with a lot of zeroes, do you ever wish that someone

+

would count the zeroes for you so you would know what the number is?

a.

2

(pos pos = pos)

Well, there is a system that does that for you. It is called "scientific

b. 2

notation." Scientific notation is a method of writing numbers in terms of

(neg pos = neg)

the powers of 10. You have already studied the powers of 10 in Lessons

1 and 4 of this subcourse.

c. 2

Basically 10P (ten to the p-th power) is a "1" followed by "P" zeroes if the

(pos neg = neg)

"P" is positive. If the "P" is negative, then "P" is the number of decimal

+

places to the right of the decimal point [decimal point followed by (P-1)

d.

2

(neg neg = pos)

zeroes followed by the numeral one (1).]

NOTE: The superscripted (raised) P (" P") is called the "exponent."

a. 10 7 is written as __________________________________
