Answer:
Negative numbers are in the opposite direction of positive numbers on the number line
Step-by-step explanation:
On the number line, the numbers on the right of zero are all positive, and the numbers on the left are all negative.
If have a profit of $3, this means you moved from $0 to $1 to $2 to $3, all on the right direction
On the other hand, a $3 loss would represent a movement to the left, which is the opposite of $3 profit. It would be written as -$3
Addition of 3 is +3
The opposite would be subtraction of 3, which is -3.
Finally, a negative number is the opposite of a positive number.
