Explicație pas cu pas:
[tex]a = [ 10 - ( 7 \times 13 - 1 ) : 9 ] \times 2016 = [ 10 - (91 - 1 ) : 9 ] \times 2016 = ( 10 - 90 : 9 ) \times 2016 = ( 10 - 9 ) \times 2016 = 1 \times 2016 = 2016[/tex]
[tex]b = [ (3 \times 11 + 8 \times 11) : 11 - 1 ] \times 3 = [11(3 + 8) : 11 - 1] \times 3 = (11 \times 11 : 11 - 1) \times 3 = (11 - 1) \times 3 = 10 \times 3 = 30[/tex]
[tex]c = ( 1 + 2 + 3 + ... + 10 ) : 11 = \frac{10 \times 11}{2} : 11 = \frac{10 \times 11}{2 \times 11} = \frac{10}{2} = 5[/tex]
