Is subtraction a short cut for addition?
No, subtraction is not a short cut for additon. In addition, you add numbers to another number to make it bigger. For example, adding 2 to 3 gives you 5. You can see that 5 is bigger than 2 and 3. However, for subtraction, you take away numbers to make a number smaller. If you take away 2 from 5, you get 3. As you can see, 3 is smaller than 5, which proves that subtraction makes a number smaller.
Does a negative number plus a negative number equal a negative?
Yes it does. Because the it acts like subtraction, but since the positive, negative number scales run backwards like a mirror, subtraction is addition with two negative numbers.
What do rational and irrational numbers have in common?
Rational and irrational numbers are part of the set of real numbers. There are an infinite number of rational numbers and an infinite number of irrational numbers. But rational numbers are countable infinite, while irrational are uncountable. You can search for these terms for more information. Basically, countable means that you could arrange them in such a way as to count each and every one (though you'd never count them all since there is an infinite number of them). I guess another similarity is: the set of rational numbers is closed for addition and subtraction; the set of irrational numbers is closed for addition and subtraction.

However, for subtraction, you take away numbers to make a number smaller. If you take away 2 from 5, you get 3. As you can see, 3 is smaller than 5, which proves that subtraction makes a number smaller.
