Give examples of positive rational integers

Define a positive rational number

The name positive rational number is given to any number that we can represent by the division of one positive integer by another. Numbers that cannot be designated by the division of one integer by another are termed irrational.

Give examples of negative integers

-1, -2, -3 and so on.

Is zero an integer?

Yes, but is neither positive nor negative

Define the absolute value of a number

Define the reciprocal of a number

The reciprocal of any number is one divided by that number.

What is the commutative law of addition?

Commutative law of addition: The sum of two numbers is the same regardless of the order in which they are added A+B=B+A

What is the associative law for addition?

Associative law for addition: The sum of three or more numbers is the same regardless of how they are grouped for addition A + (B + C) = (A + B) + C

Write in symbolic form the associative and commutative laws of multiplication

Commutative AB = BA Associative A(BC) = (AB)C

Give an example of the distributive law

Distributive law 4(3+5) = 4*3 + 4*5 OR A*(B + C) = A*B + A*C
