| INTEGER
SUBTRACTION RULES
 | First, change the problem into an addition
problem. Then use the rules for addition ....
|
| If both of the integers are positive, add their values and
prefix the number with a positive sign.
|
| If both of the integers are negative, add their absolute
values and prefix the number with a negative sign.
|
| If one integer is negative and one integer is positive,
subtract the integers, and use the sign of the integer with the largest absolute value.
|
Examples:
14 - (-6) = 14 + 6
= 20
-14 - 6 = -14 +
(-6) = -20
-14 - (-6) = -14 + 6
= -8 |
