Addition Positive + PositiveNegative + NegativePositive + NegativeNegative + Positive = (-4) = (-4) = = 2

Subtraction Positive – PositiveNegative – NegativePositive – NegativeNegative – Positive = (-4) = 22 - (-4) = = -6

Multiplication Positive Negative Positive NegativeNegative Positive 2 4 = (-4) = 82 (-4) = = -8

Division Positive ÷ PositiveNegative ÷ NegativePositive ÷ NegativeNegative ÷ Positive 2 ÷ 4 = ½ - 2 ÷ (-4) = ½2 ÷ (-4) = -½ -2 ÷ 4 = -½
