What is the total of adding each number 1 to 100?

The total of adding each number from 1 to 100 can be calculated using the formula for the sum of an arithmetic series: ( S = \frac{n(n + 1)}{2} ), where ( n ) is the last number in the series. For the numbers 1 to 100, ( n = 100 ). Thus, the sum is ( S = \frac{100(100 + 1)}{2} = \frac{100 \times 101}{2} = 5050 ). Therefore, the total is 5050.
