Scientific Notation: Addition And Subtraction 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. ... Step 2: Add or subtract the numbers. Step 3: Give the answer in scientific notation.

To ADD or SUBTRACT numbers written in scientific notation: The numbers MUST have the same exponent on the powers of 10. To increase an exponent in scientific notation, move the decimal point in the mantissa to the left the same number of times that you would like to increase the exponent.

To be added or subtracted, two numbers in scientific notation must be manipulated so that their bases have the same exponent--this will ensure that corresponding digits in their coefficients have the same place value.

To add or subtract quantities in scientific notation, numbers are manipulated so that they contain similar bases and exponents. This is done in order to ensure the corresponding integers in their coefficients are in the same place value.

The exponent tells you how many times ten is to be multiplied by itself to equal the number you wish to write. Scientific notation is the way that scientists easily handle very large numbers or very small numbers. For example, instead of writing 0.0000000056, we write 5.6 x 10-9.
