give two examples that show how using parentheses can change the order in which operations are performed in an expression

Verified Answer :

Example  1.
(402) - 8/12

Simplify 40×2 to 80

80−\(\frac{8}{12}\)

 Simplify
\(\frac{238}{3}\)

Example 2.
40(2 -8/12)

Simplify

40(2-\(\frac{2}{3}\))
which is 40 x \(\frac{4}{3}\)

Simplify once more and your answer is \(\frac{160}{3}\)
