$\snippet{name: op_column, sign: '+', x: '3,537', y: '5,463', z: '9,000 '}$
12,28 − 6,938
$\snippet{name: op_column, sign: '-', x: '12,280', y: '6,938', z: '5,342 '}$
8 − 4,659 = 3,341
$\snippet{name: op_column, sign: '-', x: '8,000', y: '4,659', z: '3,341 '}$
20,2 − 6,14 + 0,3 = 14,06 + 0,3 = 14,36
$\snippet{name: op_column, sign: '-', x: '20,20', y: '6,14', z: '14,06 '}$
