When you add numbers that both have negative exponents do you add or subtract the exponents?

You would follow the order of operation and take both numbers to their exponent and then add them.
8^-2 + 6^-2
is not 14^-2, nor anything else.
you could reciprocate, then add
1/8^2 + 1/6^2
1/64 + 1/36
= 25/576

How do you subtract a positive number by a negative number?
A little awkwardly phrased, so I'll answer both ways. To subtract a negative from anything, add its positive. To subtract a positive from a negative, the equation is treated as though you are adding two postives, the result is negative.
What is the difference between scientific notation and negative exponents?
Scientific notation is a way to express very large or very small numbers. For very large exponent is positive; for very small exponent is negative. For example, 1,000,000 is 1 x 10 to the plus 6 exponent; 0.000001 is 1 x 10 to the negative 6 exponent
How can you add and subtract mixed numbers?
Make it into an both numbers an improper fraction and then do the opperation.
How do you divide a exponent?
If you have the same base on both of the exponents that you are dividing, all you have to do is subtract the exponent. For example if I have a problem like: 66/ 63, your answer will be 63.
How do you add and subtract negative and postitive numbers?
If both numbers are positive, simply add them as you learned in 4th grade. If both numbers are negative,simply add them but add a minus to the answer. If one is positive and the other negative, ignoring the signs,subtract the smaller from the larger and add the sign of the larger to your answer.

What do you with two negative exponents when multiplying?
I presume you mean you are multiplying two powers of the same base, where both exponents are negative. Regardless of the signs of the exponents, you algebraically add the exponents. For example, 2-3 times 2-4 is 2-7; 35 times 3-8 is 3-3.
