This light-hearted and catchy tune explains the rules that are used in the multiplication and division of positive and negative numbers.
Chorus:
When good things happen
to bad people, that's bad
When bad things happen
to bad people, that's good
When bad things happen
to good people, that's bad
When good things happen
to good people, that's good
The product of a positive and a negative is a negative,
When good things happen to bad people; that's bad.
The product of a negative and a negative is a positive,
When bad things happen to bad people; that's good.
The product of a negative and a positive is a negative,
When bad things happen to good people; that's bad.
The product of a positive and a positive is a positive,
When good things happen to good people; that's good.
Chorus
If the signs of both factors are the same, the product is positive.
If the signs of both factors are the not same, the product is negative.
If the dividend and divisor are both positive numbers,
The quotient is a positive number.
If the dividend and divisor are both negative numbers,
The quotient is a positive number.
If the dividend and the divisor do not have the same sign,
The quotient is a negative.
