Rule: Example
8 + (-4) = 4
(-8) + 4 = -4
Rule: Example
4 + 8 = 12
Rule: Example
(-4) + (-8) = -12
If both signs are positive.
The final sign stays the same when
the numbers are added
The final sign takes the sign of the
larger number when added

The final sign remains the same when the first
number is larger than the second.
S i g n R u l e s
The final sign becomes negative when the
first number is smaller than the second.
If both signs are negative.
The final sign becomes positive when the
first number is smaller than the second.
The final sign remains the same when the
first number is larger than the second.

number is larger than the second.
S i g n R u l e s
The final sign becomes negative when the
first number is smaller than the second.
If both signs are negative.
The final sign becomes positive when the
first number is smaller than the second.
The final sign remains the same when the
first number is larger than the second.
Rule: Example
8 - (-4) = 12
(-8) - 4 = -12
The final sign takes the sign of the first number
when subtracted.
If both signs are different AND the first
number is larger than the second number.
