Properties of Algebra

Associative Property of Addition: Rearranging the grouping of numbers does not change the sum, e.g., (3+5)+4=3+(5+4).
Commutative Property of Addition: The order of numbers can be changed without affecting the sum, e.g., x+12=12+x.
Associative Property of Multiplication: Grouping of numbers can be rearranged without impacting the product, e.g., 5*(12x)=(512)*x.
Identity Property of Addition: Adding zero to any number does not change its value, e.g., h+0=h.
Identity Property of Multiplication: Multiplying any number by one does not change its value, e.g., 53.7*1=53.7.
Commutative Property of Multiplication: The order of factors can be altered without affecting the product, e.g., a x b=b x a.
Commutative Property of Addition: Similar to multiplication, the order in addition does not affect the result, e.g., a+b=b+a.
Distributive Property: A single multiplier can distribute over an addition, e.g., 2(3+5)=23+25.
Zero Property of Multiplication: Any number multiplied by zero equals zero, e.g., 7*0=0.
Substitution Property: If two values are equivalent, one can be replaced with the other in an equation, e.g., x=6 then 2x=12.
Inverse Property of Addition: The sum of a number and its negative results in zero, e.g., 5+(-5)=0.
Inverse Property of Multiplication: The product of a number and its reciprocal equals one, e.g., 7*(1/7)=1.
Transitive Property: If one quantity equals a second, and the second equals a third, the first equals the third, e.g., if 2+4=5+1 and 5+1=6 then 2+4=6.
Symmetric Property: If one quantity equals another, then the second equals the first, e.g., if 6+3=9 then 9=3+6.
Reflexive Property: Any quantity is equal to itself, e.g., 17=17 and 10=10.

Additional Points

Identity Property of Addition: Reinforcement that adding zero keeps a number unchanged, e.g., 6 + 0 = 6.
Identity Property of Multiplication: Emphasizes that multiplying by one keeps the number the same, e.g., 3 x 1 = 3.
Associative Properties: Both addition and multiplication allow for regrouping, showing flexibility in calculations, e.g., 17 + (14 + 9) = (17 + 14) + 9 for addition.
Commutative Forms: Various illustrations show the ability to switch numbers in both addition and multiplication without altering the outcome, e.g., 34 + 84 = 84 + 34 and 35 * x = x * 35.

These properties are foundational in algebra and streamline computations in various mathematical applications.
