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

0Subtracting a negative is the same as adding the equivalent positive. For example, subtracting minus 10 is the same as adding 10.

when you add two positive integers the answer is always positive when you add two negative integers the answer is positive when you add one negative and on positive integer, the answer is negative subtracting two negative numbers gets a negative answer subtracting two positive numbers- the answer depends subtracting a negative and positive number- the answer depends, the positive number would have to be bigger than the negative to achieve a negative number, and if the positive number is less, than the answer is still negative

If you are adding a positive number, then this is the same as normal addition. For instance, 4 add positive 5 is 9. negative 1 add positive 8 is 7. If you are adding a negative number, then this is the same as subtracting that number. For instance 6 add negative 1 is 5. negative 7 add negative 2 is negative 9.

- 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.

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

You subtract a polynomial by adding its additive inverse. For example, subtracting (x - y) is the same as adding (-x + y). Alternately, you can simply subtract similar terms - that is, subtract the coefficients (the numbers) for terms that have the same combination of variables.

They aren't. The rules are the same as those for adding/subtracting or multiplying integers. Just be careful of the decimal point's location.

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.

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

Positive + Positive = Positive Negative + Negative = Negative If it's a negative + a positive, it depends on the numbers. For example: -2 + 1 = -1 -107 + 213 = 106

multiplying and dividing- positive * positive= positive positive * negative=negative negative *negative=positive subtracting- -3-6=? 1. freeze first number- -3 2.reverse the sign to a addition- -3+ 3.Reverse the sign of the number- -3+-6= -9 adding- keep the sign of the larger number, then add/subtract

None of the following rules are applicable.

Adding IntegersTo add integers, one must consider the following two rules to be a successful.If you want to think of it on the number line you start from 0 and when you add a positive number you go that much to the right, and when you add a negative number you go that much to the left. When adding two positive integers, just add like normal. When adding one positive integer, and one negative integer, it is like subtracting a positive number from a positive number. When adding two negative integers, it is like subtracting a positive number from a negative number.

to subtrct integers ,rewrite as adding opposites and use the rules for addtion of integers..

If their denominators are different then find their lowest common denominator by means of their lowest common multiple remembering to adjust their numerators accordingly before adding or subtracting.

line up the decimal point when your adding and subtracting. add annex a zero when you have extra number. sometimes you can use a number line.

To add numbers algebraically means that you consider the sign, using the common rules of algebra. For example, adding (-5) is the same as subtracting the number 5.

-You must memorize -To add 2 integers with different signs, find the difference of their absolute value -To subtract an integer, add it's opposite

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