Yes.
No.. if you write 7/2 as -7/2, then that's additive inverse property.
Additive inverse of a number a is that number which on addition with a gives 0.7 is additive inverse of -7.The property shown is additive inverse property because the addition yields 0.
Additive Inverse
The additive inverse of a number is the value that, when added to the original number, results in zero. In this case, the additive inverse of -21 would be 21, as -21 + 21 equals zero. The additive inverse is essentially the negative of the original number, so the additive inverse of -21 is 21.
the additive inverse property states that a number plus it's opposite equals zero. in other words, x + (-x) = 0 example: 5 + (-5) = 0
When a number is added to its additive inverse, the sum equals zero. The additive inverse of a number ( x ) is ( -x ), so when you calculate ( x + (-x) ), the result is ( 0 ). This property holds true for all real numbers.
