A certain stock lost six points in one day and gained nine points the next day. Write integers to represent stock’s losses and gains for two days.

So if we’re to write integers, first, we need to know what the integers are. The integers are the negative numbers, zero, and the positive numbers. But they exclude the numbers in between — so no decimals or fractions other than these numbers are written over one or adding a point zero to them. That wouldn’t change anything.

So if a stock lost six points, that would be a loss. So that would be negative points. So negative six could represent that. And in the next day, they gained — so that’s positive. They gained nine points.

Therefore, the integers to represent the stock’s losses and gains for two days would be negative six and nine.
