What is two plus two? Let's solve this step by step. We start with two blue dots representing the first number two. Then we add two red dots representing the second number two. When we count all the dots together, we get four. Therefore, two plus two equals four.
Another way to solve two plus two is using a number line. We start at the number two, shown by the blue dot. Then we add two by taking two steps forward. Each step moves us one unit to the right. After two steps, we reach the number four, shown by the red dot. This confirms that two plus two equals four.
A third way to solve two plus two is using our fingers. First, we hold up two fingers on one hand. Then we hold up two more fingers on the other hand. When we count all the fingers together, we have four fingers in total. This shows us that two plus two equals four.
In mathematics, we write two plus two as an equation. The number two, plus the number two, equals four. This is a basic addition fact that never changes. We can also see the commutative property here, which means the order of numbers doesn't matter in addition. Two plus two will always equal four.
To summarize what we learned: We solved two plus two using four different methods. First, we used visual counting with colored dots. Second, we demonstrated addition on a number line by moving forward. Third, we counted fingers to show the concept. Fourth, we wrote the mathematical equation. No matter which method we use, the answer is always four.
