2(1+0)-3=-1

Let's simplify the expression step by step:

1. Start with the original expression: \( 2(1 + 0) - 3 \).
2. Calculate the expression inside the parentheses: \( 1 + 0 = 1 \).
3. Substitute back into the expression: \( 2(1) - 3 \).
4. Multiply: \( 2 \times 1 = 2 \).
5. Now subtract: \( 2 - 3 = -1 \).

So, \( 2(1 + 0) - 3 = -1 \) is correct.
