you do not do anything when you add numbers with exponents. you just figure out the answer. it is only if you multiply numbers with exponents, where you add the exponents..
When multiplying numbers with exponents, you add the exponents.
nothing, keep the exponents the same, remember you can only add or subtract when the exponents are the same
The answer depends on what you wish to achieve.
If you are adding or subtracting two numbers in scientific notation the exponents must be the same before adding the coefficients. This is similar to 'like terms' in algebraic expressions. You can't add 5x3 and 3x2 because the exponents are not the same.

when you add mixed numbers you have a whole number but adding fraction does not.
just add the numbers
When multiplying numbers with exponents, you add the exponents.
When multiplying something with exponents, you add it. When dividing something with exponents, you subtract it.
nothing, keep the exponents the same, remember you can only add or subtract when the exponents are the same
If the base numbers or variables are the same, you add the exponents.

You should multiply the numbers, but add the exponents. For example: 92 x 27 = 189

If you are multiplying numbers with exponents, and the base is the same, you can just add exponents. For example, 104 x 105 = 109.
When adding variables with exponents, you do neither. You only add the exponents if #1 The variables are the same character (such as they are both "a") #2 You are multiplying the variables (NOT ADDING, SUBTRACTING, OR DIVIDING) Using a simple concrete case may make this clearer: 10+2 times 10+3 equals 10+5 ( 100 times 1000 equals 100,000).
