Answer 2

To solve the expression -1 + 7 + 3, you need to follow the order of operations, which is commonly remembered by the acronym PEMDAS:

1. Parentheses: Simplify expressions within parentheses first (if there were any).
2. Exponents: Evaluate any exponents (powers) if they exist (there are none in this expression).
3. Multiplication and Division: Perform any multiplication and division from left to right.
4. Addition and Subtraction: Finally, do addition and subtraction from left to right.

Now, let's solve the expression step by step:

-1 + 7 + 3

Step 1: Addition from left to right: -1 + 7 = 6

Step 2: Addition from left to right: 6 + 3 = 9

So, the result of -1 + 7 + 3 is 9.
