Suppose you have two numbers in scientific notation.
· Rename them so that the exponents (powers of 10) are the same, · add the two mantissae to form the new mantissa, and append the 10 and exponent, · if the resulting mantissa is 10 or greater then rename the mantissa and adjust the exponent accordingly.
For the first stage you may rename both numbers or either one.
For example,
3.5*10^3+ 4.5*10^4= 3.5*10^3+ 45*10^3= (3.5+45)*10^3= 48.5*10^3= 4.85*10^4
or
3.5*10^3+ 4.5*10^4= 0.35*10^4+ 4.5*10^4= (0.35+4.5)*10^4= 4.85*10^4

To add or subtract numbers in scientific notation, make sure the exponents are the same. If they are not, adjust one of the numbers by moving the decimal point and changing the exponent accordingly. Then, simply add or subtract the coefficients and keep the common exponent. Finally, write your answer in scientific notation by making sure the first digit is between 1 and 10 and adjusting the exponent if necessary.

When dividing number in scientific notation what must you do with the exponents?
Subtract them.
When dividing in scientific notation what do you do with the exponents?
When dividing in scientific notation, you subtract the exponent of the divisor from the exponent of the dividend. This will give you the exponent of the quotient after division.
What are the rules of adding subtracting dividing and multiplying written in scientific notation?
1 With addition change the scientific notation back to 'normal numbers' and then add accordingly 2 With subtraction change the scientific back to 'normal numbers' and then subtract accordingly 3 With division subtract the exponents and divide the decimals 4 With multiplication add the exponents and multiply the decimals 5 Note that if changes occur below 1 or greater than 9 in the decimal element of the scientific notation then appropriate adjustments must be made
How do you find the difference of two in scientific notation?
Convert back to standard notation. Subtract, then convert back to sci. notation.
What are the rules in adding and subtracting significant figure and scientific notation?
you take the last digit in the first one and add/subtract it to the last digit in the second one and that is your answer

Steps multiplying and adding scientific notation?
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.

How do you add and subtract numbers using scientific notation?
To add or subtract numbers in scientific notation you first need to equalise their exponents. Having done that, you carry out the addition or subtraction on the significands and append the common exponent. Then you adjust the exponent so that the significand is between 1 and 10. For example, 1.234*104 - 2.34*102 (equalise exponents) = 123.4*102 - 2.34*102 (carry out subtraction) = (123.4-2.34)*102 = 121.06*102 (adjust exponent) = 1.2106*104
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
How do you addsubtractmultiply and divide written in scientific notation?
First you have to set it to the same power of 10. Then it can easily be added or subtracted. To multiply, you just multiply the given values and add the exponent. To divide, you divide the numbers and subtract the exponent.
