1st verse:
Two different integers, the same sign
Lets say they’re both solid negative
Further left when simplified
When it’s the same sign, they combine
Express negative 3 and negative 5
Which is negative plus a negative
These two integers combine
To negative 8 when simplified
Chorus:
Oh, what’s the operation
addition, subtraction, multiplication, or division
Signs signs to tell your destination
Oh..on the number line
Yea, same signs combine yea they add together
Different signs are absolute
When we know which is bigger
One different sign can make it negative during division
And when we multiply on the number line
2nd verse:
Two different integers with different signs
Let the absolute tell you
Which is bigger by how much, this time?
Keep the sign of larger value
Express 7 and negative 9
9 is greater in the absolute
All we need to do is simplify
And we’ll find negative 2
Bridge:
So, yea multiply and/or divide
If they’re the same sign
We’ll be positive
If it’s a different sign
This will all go negative
