Exercises – Lesson 1: Printing and Numbers
Exercise 1:
Write a program that prints your name and age on one line.
Exercise 2:
Print the result of 12.5 / 3 rounded to 2 decimal places.
Exercise 3:
Display the text "AI Power Level:" followed by the number 99.876 rounded to one decimal place.
Exercise 4:
Print three numbers (4, 8, 12) separated by commas, and then print their average rounded to 2 digits.
Exercise 5:
Show a floating number formatted as currency — for example 5.6789 → "$5.68".
