1. Identify the formula for the sum of the first \( n \) natural numbers:

S = \frac{n(n + 1)}{2}

2. Substitute \( n = 790 \):

S = \frac{790(790 + 1)}{2}

3. Perform the multiplication inside the bracket first:

790 + 1 = 791

4. Multiply 790 by 791:

790 \times 791 = 624290

5. Divide 624290 by 2:

\frac{624290}{2}=312445

Therefore, the sum of the whole numbers from 1 to 790 is:

312445
