Study Notes
Basic Arithmetic
- The expression "1 + 1" represents addition.
- Addition combines two or more numbers (called addends) to find the total, also known as the sum.
- In this case, the addends are 1 and 1.
- The sum of 1 + 1 is 2.
Properties of Addition
- Commutative Property: The order of addends does not change the sum. (e.g., 1 + 1 = 1 + 1)
- Associative Property: The grouping of addends does not change the sum. (e.g., (1 + 1) + 0 = 1 + (1 + 0))
- Identity Property: Adding zero to any number does not change the number. (e.g., 1 + 0 = 1)
- Additive inverse: For any number, there is an additive inverse (opposite) that, when added together, results in zero. (e.g., 1 + -1 = 0).
Application of Addition
- Counting objects: If you have one apple and another apple, you have 1 + 1 = 2 apples.
- Measurement: If you have 1 meter and add another 1 meter, you have 2 meters.
- Financial transactions: If you have 1andearnanother1 and earn another 1andearnanother1, you have 1+1 + 1+1 = $2.
Further considerations (related to 1 + 1) in arithmetic
- The expression 1 + 1 can be considered as a fundamental building block for more complex arithmetic operations.
- This simple addition problem demonstrates the basic idea behind combining quantities.
- It showcases fundamental mathematical operations, although the outcome itself is trivial.
