我的功能

public $belanja_id,$nama_barang,$satuan,$newid;
public $updateMode = false;
public $inputs = [];
public $i = 1;
public $total ;
public $harga = [] ;
public $qty = [];

public function add($i)
{
    $i = $i + 1;
    $this->i = $i;
    array_push($this->inputs,$i);
}

public function mount($id)
{
   $belanja = $this->belanja = Belanja::findOrFail($id);
   $this->newid = $belanja->id;
   

} 

public function remove($i)
{
    unset($this->inputs[$i]);
}

public function render()
{
    $this->total = $this->harga + $this->qty;

    return view('livewire.input-belanja-lw');
}

更新此输入。我在此字段输入上使用多个输入，如何将运算数据绑定与数学运算一起使用，这又可以是多个？ 。有人可以解决吗？
