Answer 1

1.     Calculati:148+3x2979=                   323x7-87=                    2427+(561:3x4)=              924-(34:4x6)=         (396x2+7142:6)-(324-4545:7)+2742:8=
2.     Scrieti cu litere, apoi cu cifre romane:893;                                                           26788;          2894;                                                          987466   
3Aflati termenul necunoscut:9xa+38=555:5                840+16-ax7=275       (a+2624:2)x3-7x8=361           a:126=7 rest 2
4.     Transformari:9kl=?dal      90hg=?hk    42m=?mm                      9t+4q-50hg=?kg             604dl+4000cl=?l7zile+10ore=?ore    3 milenii+2secole=?ani
5.     Desenati un patrat cu perimetrul de 30 cm, apoi calulati-i aria.
