+## Code
+
+The majority of the code is written in Java and is simple. For detecting shake motion:
+Declare global variables:
+
+```java
+    switch(v.getId())
+        {
+
+            case R.id.add :
+                b = Integer.valueOf(etn1.getText().toString());
+                etn1.setText("");
+                 c = a + b;
+                break;
+
+            case R.id.sub :
+                etn1.setText(null);
+
+                b = Integer.valueOf(etn1.getText().toString());
+                c = a - b; break;
+
+            case R.id.mul :         etn1.setText(null);
+
+                b = Integer.valueOf(etn1.getText().toString());
+                c = a * b; break;
