0There are different rules for different operations.

Up your bum.

Because adding any set of real numbers together will result in another real number.

Make sure that one of them is 2.

Same rules as adding whole numbers with different signs.

Find the sum of two mixed numbers by applying the procedure for adding mixed numbers, Solve a real-world problem by subtracting mixed numbers.

Line up the numbers and add from left to right. If you you have remainders put on top of the next right number and add to sum

Wats are temples from South East Asia and, as far as I am aware, they do not dicatate any rules for adding rational numbers.

When people started classifying numbers in different ways Some numbers were grouped together and called Real numbers. Solutions that would create Imaginary numbers were simply explained away as impossible, later the rules for working with these numbers, but, even though they are not considered Real numbers some math operations will create Real number answers.

adding fractions is like adding a WHOLE lot of parts of numbers

what is the rule in adding rational numbers

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

There are many. There are those that deal with the four basic binary operations, then there are rules governing exponents and logarithms.

- when adding or subtracting in scientific notation, you must express the numbers as the same power of 10. This will often involve changing the decimal place of the coefficient.

The result of adding two numbers is their sum.

when you add mixed numbers you have a whole number but adding fraction does not.

natural numbers are used in real life for counting, adding, subtracting and even for calculting money purposes

Yes it is. All pure imaginary numbers (such as 5i) as well as all real numbers and any combination of real & imaginary (by adding, subtractin, multiplying, dividing) makes a complex number.

The set of real numbers is closed under addition, subtraction, multiplication, and division (except that you cannot divide by zero). By closed, this means that if the two numbers in the operation are both real numbers, the result of the operation will always be a real number. Dividing by zero is undefined (for all practical purposes)

When subtracting negative numbers change the subtraction sign to a plus and change the second number (which would appear to be positive) to a negative. ex. -14 - 7=?/-14 + -7= -21 When adding negative numbers just add them as they appear. ex. -2 + -5= -7

Ensure that the denominators are the same when adding or subtracting fractions.

rules of operation sign of numbers

Mixed numbers can be converted to improper fractions. Then, it is exactly the same as adding proper ones.
