Đề kì quá :(( Tới 12 là hết chưa?

Hảo đề . Sau 12 còn cộng thêm j ko?

45-56=-11

78-90=-12

566-709=-143

45 - 56 = 45 + ( - 56 ) = ( - 56 ) - 45 = -11

78 - 90 = 78 + ( - 90 ) = ( - 90 ) - 78 = - 12

566 - 709 = 566 + ( -709 ) = ( - 709 ) - 566 = - 143

x + 45 = 58

x        = 58 - 45

x        = 13

x + 78 = 90

x         = 90 - 78

x         = 12

x+45=58
x     =58-45
x     =13

x+78=90
x     =90-78
x     =12    

 Số 0 sai rồi 12^x không bao giờ có số tận cùng là 0 đâu
