Compute the value 1. Are you sure you want to delete this answer? A value raised to a negative exponent is the same as the reciprocal of the value raised to a positive exponent. Any value raised to the zero power is 1. I'm a math teacher. That is the computed value, and to write it with a positive exponent, simply raise it to Well, negative exponents are almost the same as positive exponents.

So, to solve the equations, just put the negative exponents into the denominator. Also, any number raised to the power of 0 is 1.

The sum is 3. However, if -8 and 3 are added, the sum is In terms of the number line, -8 is further to the left than 3 is to the right. Speaking math language, if a positive number is added to a negative number and the absolute value of the negative number is larger, the sum will be negative. Figure 3: Addition of positive and negative numbers.
