What is the additive inverse of 157 ? Answer:

The additive inverse of a number is what you would add to that number to get a sum of zero. For 157, the additive inverse is -157. So, if you add 157 and -157 together, you get 0! It's like having a balance scale - one weight on one side is perfectly countered by an equal weight on the other side. This concept isn’t just confined to textbook math; it’s widely used in real-world scenarios like finance, where you balance positive and negative transactions. For example, if you earn $157 and then have an expense of $157, your net money remains zero, showing how additive inverses can help keep track of balance in budgets!
