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
Fractional exponents follow the same rules as integral exponents. Integral exponents are numbers raised to an integer power.
No you add them if the bases are the same.

When multiplying something with exponents, you add it. When dividing something with exponents, you subtract it.

Fractional exponents follow the same rules as integral exponents. Integral exponents are numbers raised to an integer power.
You subtract the exponent of the divisor from that of the dividend.
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).
You write down the numbers you want to add and subtract, making sure the decimal points are aligned. Then, you add (or subtract) EXACTLY as you would add or subtract integers. The decimal point in the solution should be aligned with the decimal points in the original numbers.
No you add them if the bases are the same.
When adding or subtracting numbers in scientific notation, ensure that the exponents are the same. If the exponents are not the same, adjust one or both numbers to match. Then, add or subtract the coefficients while keeping the exponent the same. Finally, simplify the result if necessary by converting it back to proper scientific notation.
when you add numbers, you get a sum. when you subtract numbers, you get a difference. (also in multiplication it's product, and in division is quotient.)
The calculator is the most common machine to add and subtract numbers. Computers are also very good at this and are adding and subtracting for us all the time.
