Q. Which property of addition is shown?1+(7+6)=(1+7)+6Choices:(A)associative(B)commutative
Identify Structure: Identify the structure of the equation. The equation is 1+(7+6)=(1+7)+6. This shows a rearrangement of parentheses without changing the order of the numbers.
Compare Properties: Compare the equation to the properties of addition.The associative property allows us to change the grouping of numbers in an addition problem without changing the result. This matches our equation where only the grouping (parentheses) changes.
Verify Calculation: Verify the calculation for correctness.Calculate both sides:Left side: 1+(7+6)=1+13=14.Right side: (1+7)+6=8+6=14.Both sides equal 14, confirming the property used does not affect the sum.
