In a general sum:
A + B + C
each of these elements is called an addend.
In this problem we want to add:
-1.5 + 1.75
The first addend is -1.5, the second addend is 1.75.
First let's solve this, notice that the first element is negative and the second is positive, so we can rewrite our sum as:
-1.5 + 1.75 = 1.75 - 1.5 = 0.25
Now we want to plot the first addend (-1.5 ) and the sum of the numbers (0.25)
