Best Answer

in adding scientific notations you have to make their exponents the same then add the numbers. after you add coppy th x 10 and its exponent

ex.

1.25 x 10e10 + 7.5 x 10e9

=1.25 x 10e10 + 0.75 x10e10(you can see that the decimal point is move to the left so that its exponent will be equal)

=2.0 x 10e10(final ans.)

Rules in adding or subtracting scientific notation?

When adding or subtracting numbers in scientific notation, ensure that the exponents are the same. If the exponents are not the same, adjust one or both numbers to match. Then, add or subtract the coefficients while keeping the exponent the same. Finally, simplify the result if necessary by converting it back to proper scientific notation.


What are the rules writing of scientific notation?

In scientific notation all numbers are written in the form: a*10b where a is a decimal number such that 1 ≤ a < 10 and b is an integer.


What are the rules when expressing a long mathematical expression to scientific notation form?

Scientific notation is of little use for long mathematical expressions. It is used to express very large or very small numbers - not expressions.


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


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

What rules do we use to convert standard to scientific notation?

Standard notation (in the UK) is the same as scientific notation. So the one rule to use is DO NOTHING!


How to write the rules in writing standard notation to scientific notation?

I don't know what you mean "how to write the rules." In the US, "standard" notation means "long form", i.e. 6,000,000, while "scientific" notation means the exponential form, 6x106. I had thought it was the same in the UK, but Mehtamatics says otherwise: "Standard notation and scientific notation are the same in terms of UK usage of these phrases."

What are the rules in adding scientific notation?

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


Are Scientific notation is a way of making numbers scientific?

Scientific notation is a useful way of dealing with very large and very small numbers. It allows them to be presented in a form where their magnitude can be seen more easily. Also it can simplify calculations by allowing you to concentrate on the significant digits rather than the orders of magnitude which are very easily dealt with. This latter advantage has somewhat diminished with the widespread availability of calculators and computers. But previously people used log tables and slide rules for multiplication and division. These calculating devices depended on thinking of numbers in their scientific notation.


What are rules of adding subtracting dividing multiplying scientific notation?

Addition and Subtraction in Scientific NotationA number written in scientific notation is written as the product of a number between 1 and 10 and a number that is a power of 10. That is, it is written as a quantity whose coefficient is between 1 and 10 and whose base is 10.Addition and SubtractionOne of the properties of quantities with exponents is that numbers with exponents can be added and subtracted only when they have the same base and exponent. Since all numbers in scientific notation have the same base (10), we need only worry about the exponents. 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.Multiplying a number by another number with the same base is equivalent to multiplying their coefficients and adding their exponents. Therefore, if we want to add two quantities written in scientific notation whose exponents do not match, we can simply write one of the powers of 10 as the product of two smaller powers of 10 , one of which agrees with the other term.Alternately, if we want to preserve the exponent of the term with the larger power of 10 , we can simultaneously multiply and divide the other term by a power of 10 , applying the rule for multiplication of exponents in one case and dividing the coefficient in the other. It is this procedure that we outline below. Once the numbers have the same base and exponents, we can add or subtract their coefficients.Here are the steps to adding or subtracting numbers in scientific notation :1. Determine the number by which to increase the smaller exponent by so it is equal to the larger exponent.2. Increase the smaller exponent by this number and move the decimal point of the number with the smaller exponent to the left the same number of places. (i.e. divide by the appropriate power of 10 .)3. Add or subtract the new coefficients.4. If the answer is not in scientific notation (i.e. if the coefficient is not between 1 and 10) convert it to scientific notation.Multiplication and Division in Scientific Notation Multiplication and DivisionQuantities with exponents can be multiplied and divided easily if they have the same base. Since all number in scientific notation have base 10 , we can always multiply them and divide them.To multiply two numbers in scientific notation, multiply their coefficients and add their exponents. To divide two numbers in scientific notation, divide their coefficients and subtract their exponents. In either case, the answer must be converted to scientific notation.Here are the steps to multiply two numbers in scientific notation:1. Multiply the coefficients--round to the number of significant figures in the coefficient with the smallest number of significant figures.2. Add the exponents.3. Convert the result to scientific notation.Here are the steps to divide two numbers in scientific notation:1. Divide the coefficients--round to the number of significant figures in the coefficient with the smallest number of significant figures.2. Subtract the exponents.3. Convert the result to scientific notation.
