Q. Which property of addition is shown?\newline9+1=1+99 + 1 = 1 + 9\newlineChoices:\newline(A) associative\newline(B) commutative\newline(C) identity
  1. Identify Property: Identify the property of addition shown by the equation 9+1=1+99 + 1 = 1 + 9.
  2. Compare to Properties: Compare the equation to the properties of addition:\newline- Associative property: (a+b)+c=a+(b+c)(a + b) + c = a + (b + c)\newline- Commutative property: a+b=b+aa + b = b + a\newline- Identity property: a+0=aa + 0 = a\newlineThe given equation matches the form a+b=b+aa + b = b + a, which is the commutative property.
