It is possible to make every letter and number with matchsticks because numbers and letters are made with straight lines and matchsticks also resemble straight lines. Matchsticks can be placed in different positions to make them resemble numbers and letters. Hence, there isn’t any number or letter that cannot be made with a matchstick.All numbers starting from 1 can be written using straight lines. Some of the numbers are 1, 5, 10, 60, etc.
