Figure 1-3. The exponent indicates the number of times the number is

multiplied by itself.

(1) The small raised number, or exponent, indicates how many times the

number should be multiplied by itself. The first example, shown above, is ten to the

fourth power. Ten multiplied by itself four times is l0xl0xl0xl0 or 10,000. The next

example, ten to the third power, is l0xl0xl0 or 1000. Ten to the second power (ten

squared) is l0xl0 or 100. Ten to the first power is 10. Note, that any number to the first

power is the number itself.

Figure 1-4. Any number to the first power is the number itself.

(2)

And any number to the zero power is, by definition, one.

Figure 1-5. Any number to the 0 power is 1.

(3) Now, calculate powers of 2 for yourself in figure 1-6, following the

example provided at figure 1-3. (The answers are provided at figure 1-8.)
