2-(-1)= 2+1= 3 When a parenthesis is preceded by a minus sign, remove the parentheses and the minus sign before the parentheses and change the sign of each term within the parentheses. When a parenthesis (-1) is preceded by a minus sign, -(-1) remove the parentheses ( ) and the - sign before the parentheses and change the sign of each term -1 within the parentheses +1
You change the sign of each of the terms inside the parentheses. For example:- (a - b + c)becomes:-a + b - c
A "+" before parentheses means + 1 times everything inside, so +(a+b-c) means +a+b-c
Remove the negative first and connect it back up last.
First remove the Negative cable first, and then you can remove the positive cale safely. Al
You have to switch the sign of all terms within the parentheses. For example, -(a - b + c - d) becomes -a + b - c + d
Always remove the negative (-) cable first. When connecting it back up connect the negative last.
The negative cable is removed first, then the positive. To re-connect, the positive goes first, then the negative.
It is recommended to remove the negative first. It causes less of a voltage spike if the ground is removed first.
Remove the parentheses and change the sign of everything that was within them. Eg: 25 - ( 6 + 4 - 8 + 2) ( which is 25 - (4)) becomes 25 - 6 - 4 + 8 - 2 = 21
When you have a minus sign in front, to remove parentheses each of the terms inside the parentheses changes sign. Example:a - (b - c + d) = a - b + c - d
