 ###改善したいこと
 if文の書き方が的確でないため意図しない結果になっていると思うのでどのようにif文を書けばいいかを知りたい。
+### 現コード
+```swift
+@IBAction func tapNum(_ sender: Any) {
+        //let text = (sender as AnyObject).tag == 10 ? "+" : String((sender as AnyObject).tag)
+        var text: String

+        }else{
+            text = String((sender as AnyObject).tag)
+        }
+        dataSource.upDate(value: text)
+        labelUpdate()
+        let num: Double = Double(dataSource.pText)!

+色々試してみましたがどうしても意図したタイミングで計算されません。
+処理の流れやどこを直せばいいか知りたいです。
