Assuming that "forth" is your attempt to spell fourths, the answer is eleven and two fifths.
11 and 2/5
The sum of 2/3 and 1/5 is 13/15.
the sum of 2 plus 2 is 4/2+2=44
2
Sum = Addition 2 + 2 = 4
One fifth plus one fifth is two fifths (2/5).
The sum is 6.
Sum = 79*(79+1)/2 = 79*80/2 = 3160
When the sum of a number plus 3 is squared, it is 11 more than the sum of the number plus 2 when squared.
if (n%2==0) sum=n/2*(n+1); else sum=(n+1)/2*n;
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.
