a + d
D + D = M
"the same as the others added together" For example: a=b+c+d a is equal to the sum of b plus c plus d. 9=2+3+4
4x2 -x -1 :D
6+6=12, easy :D
Unless the values of the things will no be know things, then the sum will also not be known
Expressed as a sum in hexadecimal form, F + D = 1C.
Omg I think I know! 73! Just kidding 75. :D
No; it is false. The sum of all the angles of a quadrilateral always equals 360o.
The sum answer = 3440
The sum is 1511.
The sum of 3 plus 4 is 7.
The sum of 75 plus 5 is 80.
