📚 Integer Rules

➕ Adding Integers

Same signs?
ADD & keep the sign
−3 + (−4) = −7
Different signs?
SUBTRACT & use larger sign
−7 + 3 = −4

➖ Subtracting Integers — KCC Rule

KEEP · CHANGE · CHANGE
Keep the first number  ·  Change subtraction → addition  ·  Change the sign of the second number
Example:   5 − (−3)  →  5 + 3  =  8

✖️ ➗ Multiply & Divide Integers

Same signs → POSITIVE
(+)(+) = +  |  (−)(−) = +
Different signs → NEGATIVE
(+)(−) = −  |  (−)(+) = −
