tentukan hasil operasi hitung campuran berikut! a. 12+5×10:2 b. 14:2+10×3-(-5)

a. 12+5: 17×10 :170:2=85
b. 14:2 = 7 + 10 = 17× 3= 51+ 5 = 56
semoga membantu....

a.
12 + 5 x 10 : 2
= 12 + ( 5 x 10 ) : 2
= 12 + ( 50 : 2 )
= 12 + 25
= 37

b.
14 : 2 + 10 x 3 - (-5)
= 14 : 2 + 10 x 3 + 5
= ( 14 : 2 ) + ( 10 x 3 ) + 5
= 7 + 30 + 5
= 37 + 5
= 42
