It wasn't necessary to 'create' any rules. They

follow logically from the definition of exponents.

0When multiplying something with exponents, you add it. When dividing something with exponents, you subtract it.

1. Find the value of the exponent. 2. Multiply or divide normally.

One use is shorthand for large numbers, eg the mass of the earth is 5960000000000000000000000 kg , which can be expressed as: 5.96 * 1024 kg there are also rules for multiplying / dividing exponential numbers

Multiply the mantissas, add the exponents. Normalize the result, if desired.

The question has no sensible answer because its proposition is not true. Multiplication is commutative, division is not, so the rules are NOT the same.

The rules are not the same.Multiplication is commutative whereas division is not.Multiplication is associative whereas division is not.

Adding integers, if they have the same sign, add their absolute values and keep the same sign. Subtracting, change the sign of the 2nd number and the add using rules of addition. Multiplying and dividing, Divide the absolute values, if the signs are the same the answer is positive, if the signs are different the answer is negative.

The rules are the same.

there are different rules to follow on how to multiply and divide algebraic expressions. but its basics concerns on what kind of terms you are using and the deep concern about its exponents. when you multiply or divide, it is very basic to utilize the distributive method, exponents are being added when we multiply, while subtracted when we divide.

The rules for dividing negative numbers is the same as multiplying them. A negative number multiplied/divided by a negative number is positive and a negative number multiplied/divided by a positive number is negative.

In algebraic equations, exponents can contain variables. They can be solved for by using logarithmic rules for exponents.

the rules that you have to apply when adding ,subtracting, multiplying or dividing go to this webpage for a proper explanation http://math.about.com/od/algebra/a/distributive.htm

The product or quotient of two numbers that have the same sign is positive. The product or quotient of two numbers with different signs is negative.

Fractional exponents follow the same rules as integral exponents. Integral exponents are numbers raised to an integer power.

Multiplication and addition are different mathematical operations with different rules. What is required for addition is not necessarily required for multiplication.

The product rule says when multiplying two powers that have the same base, you can add the exponents. There are product rules used in calculus to find the product of derivatives, but that does not really have to do with exponents.The above answer translates to the following Algebra rule:xm * xn = xm+nHere is an example:x5 * x2 = x5+2 = x7

positive x positive = positive negative x negative = positive positive x negative = negative negative x positive = negative The same rules apply for dividing, since dividing is actually multiplying by the reciprical.

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

Because it is.

You do the multiplication or division using the absolute value - without worrying about the sign. Then, when you have got the answer, you apply the rules for signs to decide whether your answer should be positive or negative.

It will be the same as dividing positives but if it is a negetive divided by a postive the answer will still be negative
