The addition equation or a subtraction equation to describe the diagram is (-9)—(-4) = -13
What is an arithmetic operation?
It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
We have a line graph shown in the picture.
The small arrow represents the length of 4 but as it is indicating negative direction, so we take -4
Similarly, the big arrow represents the length of 9 as it is indicating negative direction, so we take -9
The sum of the lengths:
(-9)—(-4) = -13
Thus, the addition equation or a subtraction equation to describe the diagram is (-9)—(-4) = -13
