to subtract a positive integer :move LEFT. The answer will get smaller
Yes, because subtrating a negative number is the same thing as adding a positive number.
Unless the integer is fractional it is not an irrational number.
You look at the sign before a number and that tells you what is to be done to the number that follows.

To subtract a negative number is equivalent to adding a positive number. Two negatives multiplied make a positive.

You will get a positive integer. If you subtract a negative number, you will be adding it. I think of it like 2 minuses equals a plus. :P
That would be false. When you subtract two positive numbers, you only go into negatives if the number you are subtracting is greater than the number it's being subtracted from. 3 - 2 = 1 2 - 3 = -1
The number was less than -2, for example - 3,000,000 -3,000,000 -(-2) = -3,000,000 + 2 = -2,999,998
An integer is a whole number without decimals or fractions
The number 4 is an integer (the Number 4.1 is a real number and not an integer) The number 2 is an integer (the number 2.9 is a real number and not an integer) 4-2 = 2 4+2 = 6 The above are examples of how the integers 4 and 2 can be added or subtracted.

No. To be a rational number it must be an integer over another integer. π is not an integer, nor can it be made into an integer by multiplying it by another integer, thus one twelfth of π is not a rational number.
Unless the integer is fractional it is not an irrational number.
