2. Gunakan rumus ini : (-) + (-) = (-)
. 4.650
. 7.279 +
– 11.929
3. Gunakan rumus ini = (-) × (-) = (+)
. 52
. 15 ×
780
4. Gunakan rumus ini : (-) : (+) = (-)
736 : 23 = (- 32)
5. (a : (-c)) × (-b : c) = …
= (-85:(-5)) × (-35:5)
= 17 × (-7)
= -119
6. 50 – 75 × (-4) + 184 : 8 = …
= 50 – (75 × (-4)) + 184 : 8
= 50 – ((-300) + 23)
= 50- (- 277)
= 327
7. 15 × ⅗ – (- 2) = …
= (15 × ⅗) – (-2)
= 45/5 – (-2)
= 9 -(-2)
= 11
8. 46 × (23 × a) = (46 × 23) + (46 × 13)
a = 13
