Tlng bantu yaa besok di kumpul 1. (9 : -3) + 10 - (-5) 2.8 -12 : (4 - 2) 3. 1 + 2 - 7 x 5 4. (5-2) x 2 +(8-3) Bantu ya

1. (9:-3) + 10 - (-5)
=-3 + 15
=12
2. 8-12 : (4-2)
=8 - 12 : 2
=8-6
=2
3. 1+2 - 7 x 5
=1 + 2 - 35
=3-35
=-32
4. (5-2) x 2 + (8-3)
=3 x 2 + 5
=6 + 5
=11

1.(9:-3)+10-(-5)=(-3)+15=12
2.8-12:(4-2)=8-12:2=8-6=2
3.1+2-7x5=1+2-35=3-35=-32
4.(5-2)x2+(8-3)=3x2+5=6+5=11
