Only assignment, call, increment, decrement, await, and new object expressions can be used as a stat

Can someone help show me how to fix these errors?

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine.UI;
4. using UnityEngine;
5.  
6. public class Functions : MonoBehaviour {
7.  
8.     public int wins = 0;
9.     public int RandomValue = 0;
10.     public int TimesPlayed;
11.     public int TotalEarnings = 0;
12.     public float WinAverage = 0;
13.     public float WinPercentage = 0;
14.     public Button Button1;
15.     public Button Button2;
16.     public Button Button3;
17.     public Text GamesPlayed;
18.     public Text WinPercent;
19.     public Text WinAve;
20.  
21.  
22.     // Use this for initialization
23.     void Start () {
24.         GamesPlayed.text = "0";
25.         WinPercent.text = "0";
26.         WinAve.text = "0";  
27.     }
28.    
29.     // Update is called once per frame
30.     void Update () {
31.        
32.     }
33.     public void Play()
34.     {
35.         GenerateRandom;
36.         TimesPlayed;
37.         PrizeWon;
38.         CalculateAverages;
39.         GamesPlayed.text = TimesPlayed.ToString();
40.         WinPercent.text = WinPercentage.ToString();
41.         WinAve.text = WinAverage.ToString();
42.     }
43.     public void GenerateRandom()
44.     {
45.         RandomValue = Random.Range(1,11); //10
46.     }
47.     void WonGame()
48.     {
49.         wins += 1;
50.     }
51.     void GamePlayed()
52.     {
53.         TimesPlayed += 1;
54.     }
55.     void PrizeWon()
56.     {
57.         TotalEarnings += 2;
58.     }
59.     void CalculateAverages()
60.     {
61.         WinPercentage = wins / TimesPlayed;
62.         WinAverage = TotalEarnings/TimesPlayed;
63.     }
64.        
65.        
66. }
67.  

 

You have things like:
PrizeWon;
when you need:

Code (csharp):

1.  PrizeWon();
