Answer:
4
Step-by-step explanation:
Lets start with addition.
Addition is the action or process of adding something to something else.
To add 2 and 2, we can use the number line. If you start at 2, and jump 2 places, you'll land at 4.
Numbers are in the order, 1,2,3,4,5,6,7,8,9,10
If you jump from two two times, you'll land at four.
<h2>You can also subtract to find your answer!</h2>
Simply subtract 4 from to, and you end up with 2, so 2+2=4.
To do this, start at 4 and go backwards on the number line.
