Hello everyone, first of all I am sorry for any mistakes in my message. My English is not perfect yet.
I have a question which exactly looks like this:
2(x-3(x-2)) so it is mainly about the use of parenthesis in Maths. Very basic question.
While solving this question, I start with parenthesis as it's how it should be according to order of operations and multiply (x-2) by 3, and have 3x-6. But when I look at the answer, I see they multiply -3 by (x-2).
The problem is, I see that - as minus, rather than negative sign. Because as far as I know if it were negative then it was supposed to be written as (-3) in order to avoid a confusion.
Now, how am I supposed to know if that (x-3(x-2)) is x minus 3 times (x-2), or x times negative 3 times (x-2)?
I know it is a very basic question but I recently started learning Maths and it probably explains my confusion. Am I supposed to take the operation sign, which is minus here, into consideration while multiplying 3 by (x-2), or is it already negative 3 there? How can I distinguish these two if they write them the same in the question?
Thank you for your help and have a nice day!
