Question

Oblicz wartości wyrażeń; 35x12+71x4= 85x19-1190:7= 101x96-34x12= 1728:16-13x7= 2688:12+630:14= 4738:23-1054:17= [15+7]x[38-15]= 15+[7x38-15]= 15+[7x38-15]= 15+7x38-15= [15+7x38]-1= 15+7x[38-15]=

Answer 1

35*12+71*4= 420+ 284= 704.
85*19-1190:7= 1615- 170= 1445.
101*96-34*12= 9696- 408= 9288.
1728:16-13*7= 108- 91= 17.
2688:12+630:14= 224+45= 269.
4738:23-1054:17= 206- 62= 144.
[15+7]*[38-15]= 22*23=506.
15+[7*38-15]= 15+ [266-15]= 15+ 251= 266.
15+7*38-15= 15+ 266-15= 266.
[15+7*38]-1= [15+266]-1= 281-1= 280.
15+7*[38-15]= 15+ 7* 23= 15+ 161= 176.
