The additive inverse of a number is what you can add to that number to get zero. In simpler terms, it’s the negative of that number.
For the number 4, the additive inverse is -4. This is because when you add 4 and -4 together:
4 + (-4) = 0
So, the additive inverse of 4 is -4. This concept is important in mathematics, particularly in operations involving integers and in solving equations.
