(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."
