Thực hiện phép tính:
a) A = ( 101 + 100 + 99 + ... + 3 + 2 + 1 ) : ( 101 - 100 + 99 - 98 + ... + 3 - 2 + 1 )
b) B = ( 37373737 x 43 - 43434343 x 37 ) : ( 12 + 22 + 32 + ... + 1002 )
B=(101+100+99+98+.....+3+2+1) / (101-100+99-98+.......+3-2+1)
B=(101+100+99+98+.....+3+2+1) / (101-100+99-98+.......+3-2+1)
