**How to Add and Subtract Scientific Notations?**

- Identify the coefficients (the numbers before the "`x10`") and exponents (the powers of `10`) of the two numbers written in scientific notation.
- If the exponents are different, adjust the exponents to be the same by moving the decimal point in the coefficient with the smaller exponent to the left or the coefficient with the greater exponent to the right. The number of places to move the decimal point is equal to the difference between the two exponents.
- Add or subtract the coefficients after adjusting the exponents to be the same.
- Write the answer in scientific notation by combining the adjusted coefficient and the adjusted exponent.
