How to make digits 1-100 with 2, 0, 2, 3

Use Excel as your calculator 123 100 Gauss realized then that his final total would be 50 = 5050 The sequence of numbers is arithmetic and when we are looking for the sum 123 100 There are two ways to approach this The first says “I know that 10 is one-tenth of 100 I will therefore divide 50 by 10 The answer is 5” This is fine

123 100 It is an Arithmetic progression with common difference 1 Therefore sum is 2 * ie * = 5050
