Explicație pas cu pas:
[tex]a = (4 + 5 \div 5 - 3) \div 2 = (4 + 1 - 3) \div 2 = (5 - 3) \div 2 = 2 \div 2 = 1[/tex]
=> a = 1
[tex]b = 11 - 6 \div [5 - 4 \div (7 - 5 \div 1)] = 11 - 6 \div [5 - 4 \div (7 - 5)] = 11 - 6 \div (5 - 4 \div 2) = 11 - 6 \div (5 - 2) = 11 - 6 \div 3 = 11 - 2 = 9[/tex]
=> b = 9
[tex]c = [(8 + 8) \div 4 - 3] \times (9 - 3 \times 3) = (16 \div 4 - 3) \times (9 - 9) = (4 - 3) \times 0 = 1 \times 0 = 0[/tex]
=> c = 0
[tex]3 \times a - b \div 3 + 3 \times c = 3 \times 1 - 9 \div 3 + 3 \times 0 = 3 - 3 + 0 = 0 + 0 = 0[/tex]
