The sum of 7 & 13 = 7 + 13 = 20
Sum of first 7 prime numbers is equal to 2+3+5+7+11+13+17 = 58.
The first 8 prime numbers are 2, 3, 5, 7, 11, 13, 17, and 19. Their sum is 77.
The first seven odd numbers are 1, 3, 5, 7, 9, 11, and 13. To find their sum, you can add them together: 1 + 3 + 5 + 7 + 9 + 11 + 13 = 49. Therefore, the sum of the first seven odd numbers is 49.
The whole point of a vector is that it has a magnitude and a direction. There are no directions given in the above string of numbers.
The sum, meaning you add them together. 7+5=13.
When you add 8 and 5 the sum will be 13. On the other hand when you add 6 and 7 the sum will be 13. That's why it's equal to 13.

6 + 7 = 13(Sum means add)
13 and 5 11 and 7
13 + 23 = 36 5 + 7 + 11 + 13 = 36 2 + 3 + 7 + 11 + 13 = 36 5 + 31 = 36
The sum of 7 & 13 = 7 + 13 = 20
Sum of first 7 prime numbers is equal to 2+3+5+7+11+13+17 = 58.
30/5=613-7=6=> (13-7)*5 = 30
