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.
