Best Answer

There are four mathematical properties which involve addition. The properties are the commutative, associative, additive identity and distributive properties.

A + B = B + C Commutative property

(A+B) + C = A + (B +C) Associative Property

A + 0 = A Additive Identity Property

A*(B + C) = A*B + A*C Distributive property

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

The answer also has the same sign.

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

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.

Make sure that one of them is 2.

Same rules as adding whole numbers with different signs.

- 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.

Parentheses, exponents, multiplication and division, addition and subtraction.

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

ADDING: same sign, add and keep that sign. opposite sides, subtract their absolute values and use the sign of the number with the larger absolute value SUBRTRACTING: change the sign of the subtrahend (2nd number) then ADD using rules above.

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.

1. the opposite is another word 2. adding or taking a prefix e.g. 'un' 'in' etc 3. taking or adding the word 'not'

With both positive it's positive, with both negative it's 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.

Adding Integers To 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...

When adding a prefix, the spelling of the root word doesn't change
