5)18-17=1

Answer 2

Let's break down the expression step by step:

1. Start with the multiplication and division: 10:10 = 1 (division) 9 * 1 = 9 (multiplication)

2. Now, we can simplify the expression further: 9 + 9 - (8 + 9)

3. Perform the additions and subtractions inside the parentheses: 8 + 9 = 17

4. Now, simplify the expression further: 9 + 9 - 17

5. Finally, perform the remaining additions and subtractions: 9 + 9 - 17 = 18 - 17 = 1

So, the answer to the expression 9 + 9(10:10)-(8+9) is 1.
