1+1 equals 2. This is a basic arithmetic addition where you are combining one unit with another single unit. When you have one item and then get one more, you now have two items in total. This operation represents one of the simplest forms of counting and adding.

Extra: Addition is one of the four fundamental operations in arithmetic; the others are subtraction, multiplication, and division. In elementary mathematics, addition is used to calculate the total from two or more numbers or terms. When adding only two numbers, such as 1 and 1, it's simply combining those quantities. The concept of addition is based on combining sets: if you have one set of objects and you combine it with another set of objects, you then have a larger set that is the sum of both.

To visualize this, imagine you have one apple and someone gives you another apple. You now have one apple plus one apple, which gives you two apples. This is the essence of addition – it tells you how many items you have in total. Understanding addition is crucial because it serves as a building block for more complex mathematics that you will learn in school, like algebra and calculus.

The value of the expression 1+1 is 2. When you add the numbers 1 and 1 together, the sum is 2.

Addition is a basic arithmetic operation where two or more numbers are combined to find their total. In this case, we are adding the numbers 1 and 1. We can think of addition as counting or combining objects. When we add two numbers, we start with the first number and count up by the value of the second number. So, in the expression 1+1, we start with 1 and count up by 1, resulting in the total of 2.
