- Convert the numbers so that they all have the same index for 10.
- Calculate the subtraction for the mantissae, ignoring the powers of 10.
- Add back the power of 10 term.
- Adjust the power, if necessary, so that the mantissa of the answer is in the range [1, 10).
Example:
1.23*10^3 - 3.4*10^2
Convert them so that the power of 10 is 2:
12.3*10^2 - 3.4*10^2 = (12.3 - 3.4)*10^2 = 8.9*10^2.
{there is no need to adjust the power of 10).
Or
Convert them so that the power of 10 is 3: 1.23*10^2 - 0.34*10^3 = (1.23 - 0.34)*10^3 = 0.89*10^3 and now you need to adjust because the mantissa is less than 1. So 8.9*10^2.

How do you subtract in scientific notation?
To subtract numbers in scientific notation, first ensure that both numbers have the same exponent. If they don't, adjust one or both numbers by converting them to have a common exponent. Once they have the same exponent, subtract the coefficients (the numbers in front) and keep the common exponent. Finally, if necessary, express the result in proper scientific notation.
When dividing numbers in scientific notation what do you do with the exponents?
You subtract the exponent of the divisor from that of the dividend.
How do you add subtract multiply and divide numbers written in scientific notation?
To add or subtract numbers in scientific notation, ensure the exponents are the same; if not, adjust one of the numbers so they match before performing the operation. For multiplication, multiply the coefficients and add the exponents. For division, divide the coefficients and subtract the exponents. Finally, express the result in proper scientific notation, adjusting the coefficient to be between 1 and 10 if necessary.
What steps to do to get 0.006 in scientific notation?
6 x 10-3.
How do you subtract two negative scientific notation numbers and come out with a negative scientific notation number?
if the smaller negative sci notation # being subtracted from the larger example: (-1.0x10^0) - (-2.0x10^0) is the same as -1-(-2)= -1 + 2 = 1
What are the 7 steps of scientific notation?
There are not seven steps unless you start counting steps like "pick up pen"! Three steps is all that it takes.
What is the fourth step in scientific notation?
The answer depends on which steps you consider to be the first three. The sequence can vary.
