Study Notes
Sumas
- Concepto: Una suma es una operación matemática que consiste en combinar dos o más números para obtener un resultado.
- Símbolo: El símbolo de suma es el signo "+".
- Ejemplos:
- 2 + 3 = 5
- 5 + 1 = 6
- 7 + 2 = 9
- Propiedades:
- Conmutativa: El orden de los números no cambia el resultado. (a + b = b + a)
- Asociativa: Se puede sumar números en cualquier orden. ((a + b) + c = a + (b + c))
- Elemento neutro: La suma de un número con 0 no cambia el resultado. (a + 0 = a)
Resta
- Concepto: Una resta es una operación matemática que consiste en encontrar la diferencia entre dos números.
- Símbolo: El símbolo de resta es el signo "-".
- Ejemplos:
- 5 - 2 = 3
- 8 - 3 = 5
- 9 - 1 = 8
- Propiedades:
- No conmutativa: El orden de los números cambia el resultado. (a - b ≠ b - a)
- No asociativa: No se puede restar números en cualquier orden. ((a - b) - c ≠ a - (b - c))
- Elemento opuesto: La resta de un número con su opuesto es 0. (a - a = 0)
Relación entre sumas y restas
- La resta se puede considerar como la suma de un número con su opuesto.
- Ejemplo: 5 - 2 = 5 + (-2) = 3
Addition
- Addition is a mathematical operation that combines two or more numbers to obtain a result.
- The symbol for addition is the "+" sign.
- Examples:
- 2 + 3 = 5
- 5 + 1 = 6
- 7 + 2 = 9
- Properties:
- Commutative property: The order of the numbers does not change the result.
- Associative property: Numbers can be added in any order.
- Neutral element: Adding a number to 0 does not change the result.
Subtraction
- Subtraction is a mathematical operation that finds the difference between two numbers.
- The symbol for subtraction is the "-" sign.
- Examples:
- 5 - 2 = 3
- 8 - 3 = 5
- 9 - 1 = 8
- Properties:
- Non-commutative property: The order of the numbers changes the result.
- Non-associative property: Numbers cannot be subtracted in any order.
- Additive inverse: Subtracting a number from itself results in 0.
Relationship between Addition and Subtraction
- Subtraction can be considered as adding a number to its additive inverse.
- Example: 5 - 2 = 5 + (-2) = 3
