Study Notes

Propriedades de Pre Algebra

Proprietate Commutativ de Addition: Permite cambiar l'ordine de addition sin afectar le resultado, exempel: 3 + 4 = 4 + 3.
Proprietate Commutativ de Multiplication: Similarmente, l'ordine de multiplication non cambia le resultado, exemple: 3 × 4 = 4 × 3.
Proprietate Associativ de Addition: Le grouping de summandos non affecta le resultado, vide: (3 + 4) + 5 = 3 + (4 + 5).
Proprietate Associativ de Multiplication: Le grouping de factores non cambia le producto, exemple: (2 × 3) × 4 = 2 × (3 × 4).
Proprietate de Identitate de Addition: Addition de zero non cambia le numero, exemplo: 22 + 0 = 22 e x + 0 = x.
Proprietate de Identitate de Multiplication: Multiplicatio per uno non cambia le numero, exemplo: 8 × 1 = 8 e x × 1 = x.
Inverse Additiv: Le somma de un numero e su inverse additiv es zero, esempio: 2 + (-2) = 0 e a + (-a) = 0.
Inverse Multiplicativ: Le producto de un numero e su inverse multiplicativ es uno, exemplo: 2 × 1/2 = 1 e (2/3) × (3/2) = 1.
Proprietate de Zero de Multiplication: Multiplicatio per zero resulta in zero, esempio: 0 × 8 = 0 e 0 × f = 0.
Definition de Subtraction: Subtraction pote esser exprimit como addition de un numero negativo, exemplo: 6 - 13 = 6 + (-13).
Distributive Property: Permitte distribuere un numero in un somme, exemplo: 2(4 + 7) = (2 × 4 + 2 × 7) e x(a + b) = (x × a + x × b).
Simplification via Distributive Property: Quando combine termes, exemplo: 5x + (-3x) = (5 + (-3))x.
Variable Combinatio: Le expression ax + by = (a + b)x demonstra le uso del distributive property con variabiles.
