Answer:

No, the expression 65-(45-20) is not equal to (65-45)-20.

Step-by-step explanation:

Consider the provided expression.

Consider the expression: 65-(45-20)

Solve the above expression as shown.

65-(45-20)

65-(25)

65-25

40

Now consider the second expression.

(65-45)-20

20-20

0

Now compare both the result.

40≠0

Hence, the expression 65-(45-20) is not equal to (65-45)-20.

No, it does not. 65-(45-20) is equal to 40, because you subtract 45-20 before because of the parentheses. When you do that, you get 25 then subtract 65-25, then get 40. Then, if you subtract 65-45 first and get 25, then subtract 25-20, you'll get 5.
