Kerjakan perkalian/dalam kurung dulu..11.(28×13)+(28×7) = 364+196 =560
12.(117×12)+(117×8)=1404+936=2340
13.(24×46)+(24×26)=1104+624=1728
14.(561×(-67)) - (561×13) = -37.587 - 7.293 = 44.880
15. kerjakan yang dalam kurung dulu
121×(30-2) = 121×28 = 3.388

11.(28×13)+(28×7)
=364+196
=560
12.(117×12)+(117×8)
=1.404+936
=2.340
13.(24×46)+(24×26)
=1.104+624
=1.728
14.(561×(--67)) - (561×13)
=(-37.587)-7.293
=44.880
15.121×(30-2) ===>Dahulukan kurung
