+# Instructions
+
+Given a name and a number, your task is to produce a sentence using that name and that number as an [ordinal numeral][ordinal-numeral].
+Yaʻqūb expects to use numbers from 1 up to 999.
+
+Rules:
+
+- Numbers ending in 1 (except for 11) → `"st"`
+- Numbers ending in 2 (except for 12) → `"nd"`
+- Numbers ending in 3 (except for 13) → `"rd"`
+- All other numbers → `"th"`
+
+Examples:
+
+- `"Mary", 1` → `"Mary, you are the 1st customer we serve today. Thank you!"`
+- `"John", 12` → `"John, you are the 12th customer we serve today. Thank you!"`
+- `"Dahir", 162` → `"Dahir, you are the 162nd customer we serve today. Thank you!"`

+# Introduction
+
+Your friend Yaʻqūb works the counter at a deli in town, slicing, weighing, and wrapping orders for a line of hungry customers that gets longer every day.
+Waiting customers are starting to lose track of who is next, so he wants numbered tickets they can use to track the order in which they arrive.
+
+To make the customers feel special, he does not want the ticket to have only a number on it.
+They shall get a proper English sentence with their name and number on it.
