The answer depends on what you mean by do: add, multiply, divide, exponentiate? Do is too non-specific so, if you require want a sensible answer, you will need to ask a sensible question.
No - whole numbers only, no negatives, no fractions
Adding and subtracting negatives and positives -6+6=0 -6+-6=-12 -6+8=2 8+-7+14+-6=9 split them and do them by problem. Dividing fractions 24%-3=-8 if they are both negatives then its a positive then if there is a negative its a negative.
There are no such numbers, because every number has a decimal representation. But you can have photo negatives and photo positives which will have no fractions or decimals.
Not all negative numbers are integers. Some are fractions.
0
-1. An integer is any number that can be represented without decimals or fractions - including negatives.
You divide fractions by fractions by multiplying by the inverse. For instance, 1/3 divided by 3/4 is the same as 1/3 multiplied by 4/3, which is 4/9.
Mixed fractions are not integers. They consist of a whole number and a proper fraction. Integers, on the other hand, are whole numbers and their negatives, including zero, without any fractional or decimal parts.
Yes to a limited extent because IX = 10-1 = 9 and S = 1/2
No, its negative.
When you multiply two negatives the negatives cancel one and other out.
Similar fractions are fractions with the same denominator. 1/5, 2/5,/3/5
