Answer to Problem 37WE
Explanation of Solution
Concept Used:
While solving the expressions, first perform the operations within the grouping symbol. Then start from the left and perform the multiplication or division as it appears in the expression on going towards right. After that again start from the left and perform the additions or subtractions as it appears in the expression on going towards right.
Consider the expression,
First perform the subtraction within the parenthesis:
Now consider the expression,
First perform the subtraction within the parenthesis:
b.
To explain: is the subtraction of real numbers associative.
b.

Answer to Problem 37WE
No
Explanation of Solution
No, the subtraction of real numbers is not associative.
As for subtraction of real numbers to be associative, it must be true that for the real numbers a, b and c ,
To prove the claim that the subtraction of real numbers is not associative, consider the counter example from part (a).
As shown in part (a),
So, clearly
Hence, subtraction of real numbers is not associative.
