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
to subtrct integers ,rewrite as adding opposites and use the rules for addtion of integers..
adding and subtracting integers is when you add and minus 2 numbers
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.
there are no algorithms for subtracting algorithms!!!
Integers are whole numbers, both positive and negative. Therefore, adding and subtracting integers would be adding and subtracting whole numbers. Examples: 8+2 -8+2 8-2 -8-2
I would think that the commonality of adding and subtracting integers is that the answer itself will always be an integer. In other words, the answer is always gonna be a "whole number".
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, subtracting, multiplying, dividing
1+1 = 2 2-1 = 1
No- adding negative numbers is like adding positive numbesr , except the answer is negative.
Let x and y be two integers. x - y = x + (-y)
Subtracting a negative is the same as adding the equivalent positive. For example, subtracting minus 10 is the same as adding 10.
They become positive integers for instance - - 2 = 2
Ensure that the denominators are the same when adding or subtracting fractions.
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.
It's pretty much the exact same. Subtracting is the same as adding a negative number. Foe example, five minus three is the same as five plus negative three.
The answer will have the same sign as the number with the larger magnitude.
-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
Subtracting two positive fractional numbers, or adding one positive and one negative integer.
It can be a problem to do with adding or subtracting or exponents.
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.
When adding negative integers, you subtract. (2+-1=1) When subtracting negative integers, you add. (2--3=5)
what are some examples of subtracting integers
The answer also has the same sign.
- 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.
