= 50 + 50 + 50 + 20 + 30 + 30 + 30 + 9 – 20 – 20 – 20 – 20

= 100 + 50 + 20 + 30 + 30 + 30 + 9 – 20 – 20 – 20 – 20

= 150 + 20 + 30 + 30 + 30 + 9 – 20 – 20 – 20 – 20

= 170 + 30 + 30 + 30 + 9 – 20 – 20 – 20 – 20

= 200 + 30 + 30 + 9 – 20 – 20 – 20 – 20

= 230 + 30 + 9 – 20 – 20 – 20 – 20

= 260 + 9 – 20 – 20 – 20 – 20

= 269 – 20 – 20 – 20 – 20

= 249 – 20 – 20 – 20

= 229 – 20 – 20

= 209 – 20

= 189

kesimpulannya hasil dari 170 + 99 – 20 × 4 adalah 189

diketahui:

K = 10

I = 20

R = 30

A = 50

N = 20

ditanya:

Tentukan

K × I – R ÷ A + N

diJawab:

= K × I – R ÷ A + N

= ( 10 × 20 ) – 30 ÷ 50 + 20

= 200 – ( 30 ÷ 50 ) + 20

= 200 – 0,6 + 20

= 199,4 + 20

= 219,4

kesimpulannya hasil dari 10 × 20 – 30 ÷ 50 + 20 adalah 219,4
