Why the logical operators are not working as expected?

I am in a beginner CS course and I am trying to write a program in C that asks for a two digit number and returns the written out form of that number. I have written all of the code and it works when I try the numbers 10-19 but not any others. Compiled using C89 standard if that matters

#include <stdio.h>

int main(void)
{

printf("\n Number to Word Conversion Program");
printf("\n\n This program takes a two-digit number and outputs the English word for the number");

int number = 0;
int numberH1 = 0;
int numberH2 = 0;

printf("\n\n Please enter a two-digit number: ");
scanf("%d", &number);

numberH1 = number / 10;
numberH2 = number % 10;

if (number == 10 || 11 || 12 || 13 || 14 || 15 || 16 || 17 ||18 || 19)
{
    switch (number)
    {
        case 10:
        {
            printf("\n\n The number entered was Ten.\n\n");
        }           
        break;
        case 11:
        {
            printf("\n\n The number entered was Eleven.\n\n");
        }           
        break;
        case 12:
        {
            printf("\n\n The number entered was Twelve.\n\n");
        }           
        break;
        case 13:
        {
            printf("\n\n The number entered was Thirteen.\n\n");
        }           
        break;
        case 14:
        {
            printf("\n\n The number entered was Fourteen.\n\n");
        }           
        break;
        case 15:
        {
            printf("\n\n The number entered was Fifteen.\n\n");
        }           
        break;
        case 16:
        {
            printf("\n\n The number entered was Sixteen.\n\n");
        }           
        break;
        case 17:
        {
            printf("\n\n The number entered was Seventeen.\n\n");
        }           
        break;
        case 18:
        {
            printf("\n\n The number entered was Eighteen.\n\n");
        }           
        break;
        case 19:
        {
