Question

write an addition expression to model this picture: number line from -2 to 10 with a purple dot at 2 and an arrow to 5, and a keyboard interface below

Explanation:

Step1: Identify the starting point

The purple dot is at 2 on the number line.

Step2: Determine the movement

The arrow from 2 moves 3 units to the right (since it goes from 2 to 5, as 2 + 3 = 5).

Step3: Write the addition expression

The starting point is 2, and we add the number of units moved (3), so the expression is $2 + 3$.

Answer:

$2 + 3$
