To add or subtract two numbers in scientific notation:
Step 1: Adjust the powers of 10 in the 2 numbers so that they have the same index. (Tip: It is easier to adjust the smaller index to equal the larger index).
Step 2 : Add or subtract the numbers.
Step 3 : Give the answer in scientific notation.
To divide numbers in scientific notation:
Step 1 : Group the numbers together.
Step 2 : Divide the numbers.
Step 3 : Use the law of indices to simplify the powers of 10.
Step 4 : Give the answer in scientific notation.
To multiply numbers in scientific notation:
1. Multiply the coefficients2. Add the exponents

How do you round to a significant figure?
When adding or subtracting, follow these steps to find a sig figs answer: 1) Add/Subtract numbers regularly. 2) Determine which measurement has the least decimal places. 3) Round final answer to the same number of decimal places. When multiplying or dividing, follow these: 1) Count the number of sig figs in the numbers you are multiplying/dividing. 2) Multiply/Divide regularly. 3) Round final answer to the same number of sig figs as the measurement with the fewest sig figs.
What are the steps in writing number in scientific notation?
1.Look at the number and note where the decimal point is located 2. If it is a whole number the decimal point is at the end 3. move the decimal point to the left and place just after the first number 4. count the number of places you moved the decimal 5. The scientific notation is the number in step 3 times 10 to the power of step 4 Example: 6,000,000 = 6 times 10 to the sixth power 4,910,000.1 = 4.9100001 times ten to the sixth power 59,100 = 5.91 times ten tot he fifth power
