Seems odd that you would define all these functions inside Main(), instead of as static methods in Program. Not wrong, just want to make sure you know you do not have to do that.

How would you do this without each "sub program" calling MainMenu again?

int userChoice = 0;

Console.WriteLine("1. Divisible by 3 tool");
Console.WriteLine("2. Addition tool");

Console.WriteLine("4. Guess a number");
Console.WriteLine("5. Find largest number");

if (Int32.TryParse(Console.ReadLine(), out userChoice))
{
if (userChoice == 1)
{
Problem1();
}
else if (userChoice == 2)
{
Problem2();
}
else if (userChoice == 3)
{

}
else if (userChoice == 4)

}
