Show a pattern: 3×2=6, 3×1=3, 3×0=0, 3×(-1)=?, 3×(-2)=?. The pattern decreases by 3 each time, so: -3, -6. Positive × negative = negative! Then: (-3)×2=-6, (-3)×1=-3, (-3)×0=0, (-3)×(-1)=?, (-3)×(-2)=?. Pattern INCREASES by 3: 3, 6. Negative × negative = positive! Show 3 such patterns to discover th
