write an addition equation or a subtraction equation (your choice!) to describe the diagram.
Answer
Explanation:
Step1: Identify the numbers on the number - line
The first arrow starts from 0 and ends at 5 (assuming the un - marked tick between 3 and 6 is 5), and the second arrow starts from 5 and ends at 7.
Step2: Write an addition equation
We can write the addition equation based on the movement on the number - line. If we consider the first number as 5 and the amount we add as 2 (since 7−5 = 2), the addition equation is 5+2 = 7.
Answer:
5 + 2 = 7
