Zero; addition, subtraction, multiplication, division (The way we do today).

here is subtraction problem... 9 - 4 = 5 here is an addition of the opposite 9 + -4 = 5 both these equations are true and mean the same thing. when you subtracted you are actually adding the negative of that number. the negative means to put a minus symbol in front of that number and that number is the amount of units it takes from below zero to get to zero.

Rational numbers are closed under addition, subtraction, multiplication. They are not closed under division, since you can't divide by zero. However, rational numbers excluding the zero are closed under division.

yes when you subtract zero from anther number it equals that number example 7-0=7

In mathematics, identity is a transformation that leaves an object unchanged. In addition and subtraction, the identity element is zero. Adding or subtracting zero to or from a number will leave the original number. In multiplication and division, the identity element is one. Multiplying or dividing a number by one will leave the original number.

zero property, inverse, commutative, associative, and distributative

Any number plus zero is that number.

0, zero, is defined as the identity element for addition and subtraction. * * * * * While 0 is certainly the identity element with respect to addition, there is no identity element for subtraction. The identity element of a set, for a given operation, must commute with every element of the set. Since a - 0 ≠ 0 - a, according to group theory, 0 is not an identity with respect to subtraction.

a + 0 =aIn other words,when you add zero to a number, you get what you started with. This is called the 'addition property of zero'.

Yes. They are closed under addition, subtraction, multiplication. The rational numbers WITHOUT ZERO are closed under division.
