A mathematical sentence in addition is a statement that expresses the sum of two or more numbers. It shows the values being added together and their resulting total (sum).
Here's a more detailed explanation:
-
Definition: An addition sentence uses the addition operator (+) to combine numbers and the equals sign (=) to state the result. It represents a complete mathematical thought expressing equality between the sum and the total.
-
Components:
- Addends: The numbers being added together (e.g., in 2 + 3 = 5, 2 and 3 are the addends).
- Addition Operator: The plus sign (+) indicating addition.
- Equals Sign: The equals sign (=) showing that the sum is equivalent to the result.
- Sum: The result obtained after adding the addends (e.g., in 2 + 3 = 5, 5 is the sum).
-
Examples:
- 1 + 1 = 2
- 5 + 10 = 15
- 25 + 75 = 100
- 3 + 4 + 5 = 12 (Addition sentences can involve more than two addends)
- x + 5 = 10 (This is an algebraic addition sentence where 'x' is a variable)
-
Key Characteristics:
- It presents a complete thought showing the relationship between addends and their sum.
- It uses the addition operator (+) and equals sign (=).
- It expresses equality between the addition of the numbers and the result.
In summary, a mathematical sentence in addition clearly and completely illustrates the process of adding numbers and stating their sum in a mathematical expression.
