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.
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.
Positive x Positive = Positive: 3 x 2 = 6Negative x Negative = Positive: (-2) x (-8) = 16Negative x Positive = Negative: (-3) x 4 = -12Positive x Negative = Negative: 3 x (-4) = -12
Because it is.
In order to multiply fractions with variables, factor all numerators and denominators completely. Use the rules for multiplying and dividing fractions, cancel any common factors, and leave your final answer in factored form.
Multiplying and dividing integers and rational numbers follow the same fundamental rules. In both cases, the product of two numbers is determined by multiplying their absolute values and applying the appropriate sign rules. Similarly, division involves inverting the divisor and multiplying, maintaining the same sign conventions. Thus, the processes are consistent, with rational numbers simply extending the concept to fractions.
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.
no answer
The rules are the same.
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 mathematics, negative numbers follow specific rules for operations. When adding two negative numbers, the result is negative (e.g., -3 + -2 = -5). When multiplying or dividing two negative numbers, the result is positive (e.g., -2 × -3 = 6). However, multiplying or dividing a negative number by a positive number yields a negative result (e.g., -4 × 2 = -8).
When multiplying or dividing numbers, the result should have the same number of significant figures as the factor with the fewest significant figures. When adding or subtracting numbers, the result should have the same number of decimal places as the number with the fewest decimal places.

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
It wasn't necessary to 'create' any rules. They follow logically from the definition of exponents.
When multiplying numbers, the rules for signs are straightforward: the product of two positive numbers is positive, and the product of two negative numbers is also positive. However, when multiplying a positive number by a negative number, the result is negative. In summary, multiplying numbers with the same sign yields a positive result, while multiplying numbers with different signs results in a negative product.
