Let's solve the addition problem 1 plus 1. Addition means combining two numbers to get their sum. We start with the first number, 1. Then we add the second number, 1. The result of adding 1 and 1 is 2.
Let's visualize what happens when we add 1 plus 1. We can represent each number with an object. Here we have one circle, plus another circle. When we combine them together, we get a total of two circles. This visual representation helps us understand that one plus one equals two.
Another way to understand addition is using a number line. We start at zero on the number line. To add 1, we move one step to the right, landing at position 1. To add another 1, we move one more step to the right, landing at position 2. This confirms that 1 plus 1 equals 2.
Addition is used everywhere in our daily lives. For example, if you have one apple and you get another apple, you now have two apples in total. This is a real-world application of the addition 1 plus 1 equals 2. We use addition when counting objects, combining groups of items, or calculating totals.
To summarize what we've learned: Addition is the mathematical operation that combines two numbers to get their sum. In our example, we've shown that one plus one equals two. We can visualize addition using objects, such as apples, or using a number line where we move to the right. Addition is one of the most fundamental operations in mathematics and is used constantly in our daily lives.
