ples deh ya pake cara
Jawab:
1. (+0,5)×(-2)= -1
cara:
=(+0,5)×(-2)
=0,5×(-2)
= -0,5×2
= -1
2. (-50)×(+17)×(-2)=1.700
cara:
=(-50)×(+17)×(-2)
= -50×17×(-2)
= 50×17×2
=850×2
=1.700
3. (-5)×(-6)×(+2)=60
cara:
=(-5)×(-6)×(+2)
= -5×(-6)×2
=5×6×2
=30×2
=60
4. (3,5)×(-2)×(+9)= -63
cara:
= (3,5)×(-2)×(+9)
=3,5×(-2)×9
= -3,5×2×9
= -7×9
= -63
5. (-10)×(-10)= 100
cara:
=(-10)×(-10)
= -10×(-10)
=10×10
=100
Maaf kalo kurang jelas
