zero + zero = zero
To find the number that, when added to -15, gives a sum of 0, you can set up the equation: -15 + x = 0. Solving for x gives you x = 15. Therefore, the number you need to add to -15 is 15.

25 + 25 = 50
There is no two digit number which, when added to Y gives Y.
It is zero, by definition of additive inverse!
The additive inverse of x is -x It is the number that, when added to the original, gives a sum equal to zero.

25 + 25 = 50
There is no two digit number which, when added to Y gives Y.
Number + additive inverse of number = 0, by definition (the additive inverse of a number is that number, which when added to the original number, results in a sum of 0) Number + additive inverse of number = 0, by definition (the additive inverse of a number is that number, which when added to the original number, results in a sum of 0)
It is zero, by definition of additive inverse!
Let the number be represented as ( x ). The expression for the sum of 10 times the number and 15 added to 11 times the same number can be written as ( 10x + (11x + 15) ). Simplifying this gives ( 21x + 15 ). Therefore, the sum is ( 21x + 15 ).
Yes they are.
