Find the additive inverse of 0.7.

The additive inverse of any number 𝑎 is the number that when added to 𝑎 equals zero. As 𝑎 plus negative 𝑎 is equal to zero, then the additive inverse of 𝑎 is negative 𝑎. In this question, we need to find the additive inverse of 0.7. What number when added to 0.7 gives an answer of zero? 0.7 plus negative 0.7 is equal to zero. This means that the additive inverse of 0.7 is negative 0.7. We can go one step further by concluding that the additive inverse of any positive number is the negative of this same number.
