Вычисления:
(42 – 15) * 2 = 42 * 2 − 15 * 2 = 84 − 30 = 54
$\snippet{name: op_column, sign: '‧', x: '42', y: '2', z: '84'}$
$\snippet{name: op_column, sign: '‧', x: '15', y: '2', z: '30'}$
(31 – 8) * 5 = 31 * 5 − 8 * 5 = 155 − 40 = 115
$\snippet{name: op_column, sign: '‧', x: '31', y: '5', z: '155'}$
8 * 5 = 40
