a).9×9+9:9+9=81:1+9=90. b).45:9+5×5+45=5+25+45=30+45=75. c).63:7+5×7+23=9+35+23=44+23=67. d).36:4:3+4×4:4+30:5×7=3+4+42=49. Sper ca te-am ajutat!!!
9 x 9 + 9 : 9 + 9 = 81 + 1 + 9 = 91

45 : 9 + 5 x 5 + 45 = 5 + 25 + 45 = 30 + 45 = 75 

63 : 7 + 5 x 7 + 23 = 9 + 35 + 23 = 44 + 23 + 67

36 : 4 : 3 + 4 x 4 : 4 + 30 : 5 x 7 = 9 : 3 + 16 : 4 + 6 x 7 = 3 + 4 + 42 = 12 + 42 = 56 .                     Coronita !!!
