I really don't know but it is 12,24,36,48
The value of the answer is the sum of the absolute values of the numbers and the sign of the answer is the same as that of the two numbers.
In all of these cases the result is positive.
what is the rule in adding rational numbers
The rule in this case is that there are no numbers in any position.
Multiply it by 2 as for example 3+3 = 6 which is the same as 2*3 = 6
Add the number together and give the answer the same sign as the numbers.
The "same change" rule states that when two numbers are added or subtracted by the same amount, the result remains the same. For example, adding 5 to both 10 and 15 results in 15 and 20, respectively, which maintains a difference of 5.
If the two numbers have different signs, then the result will be negative. If the two numbers have the same signs, the result will be positive. This assumes all the numbers are non-zero.
It is one on the "index laws".
base x base result x Exponent
Wats are temples from South East Asia and, as far as I am aware, they do not dicatate any rules for adding rational numbers.
The product is positive.The rule is, "Numbers with like signs give a positive product.", and conversely, "Numbers with unlike signsgive a negative product."
