the answer is 4
If the question means solve 1+2+...+60 then 1+2+...+n = n(n+1)/2 for any integer n>0 So for n= 60 the sum is 60*61/2 = 30*61 = 1830
the sum of 2 plus 2 is 4/2+2=44
11 + 67 = 78
Sum = Addition 2 + 2 = 4
The sum is 6.
Sum = 79*(79+1)/2 = 79*80/2 = 3160
if (n%2==0) sum=n/2*(n+1); else sum=(n+1)/2*n;
When the sum of a number plus 3 is squared, it is 11 more than the sum of the number plus 2 when squared.
The sum of a number plus 3 to the square root of 9 to the sum of 2 would equal -2. This is a math problem.
