1250+300-120

1550-120

1430

Answer 2

The given expression evaluates to 1430.  

In solving the given expression, we need to know the signs in product operations :

• Positive * Positive = Positive
• Positive * Negative = Negative
• Negative * Positive = Negative
• Negative * Negative = Positive

The given expression is : $1250-(-300) + (-120)$

Step 1 : Opening the first parentheses

The operation outside the bracket is '-' and inside the bracket is '-'. Thus, according to sign rules ( - and - leads to + ).

So, the expression opening the first brackets is :

        $1250+300 + (-120)$

Step 2 : Opening the second parentheses

The operation outside the bracket is '+' and inside the bracket is '-'. Thus, according to sign rules ( + and - lead to - ).

So, the expression opening the second brackets is :

        $1250+300 -120$

Step 3 : Evaluating Operations

Now, the expression has o parentheses. Thus, we can directly solve them using BODMAS i.e. addition followed by Subtraction.

        $= 1250+300 -120\\= 1550-120\\=1430$

Hence, the given expression evaluates to 1430.
