Integer Exponents

When an exponent is positive, to calculate its value we multiply the base number by itself as many times as the exponent's value...                                example: 34 = 3 3 3 3 = 81

When an exponent is negative, it indicates that it represents a fraction. To calculate its value we  first place a one as the numerator and represent the denominator as the base number multiplied by itself as many times as the exponent's value...                                                                                        example: 3-4 =

When an exponent is one the value is always the base number.  example 31=3

When an exponent is zero the value is always one.  example 30=1
