Question

16+(-6-(18+(4-9)-2)+1)

Answer 1

16+(-6(18+(4-9)-2)+1)= -4
1 действие: 4-9= -5
2 действие:18+(-5)= 13
3 действие: -6-13= -19
4 действие:-19-2=-21
5 действие:-21+1=-20
6 действие: 16+(-20)= -4

Answer 2

To evaluate the expression 16 + (-6 - (18 + (4 - 9) - 2) + 1), we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction). Let's break it down step by step:

1. Start with the innermost parentheses: 4 - 9 = -5

2. Continue evaluating: 18 + (-5) - 2 = 18 - 5 - 2 = 11 - 2 = 9

3. Replace the expression within the parentheses with the result from step 2: -6 - 9 + 1

4. Perform addition and subtraction from left to right: -6 - 9 + 1 = -15 + 1 = -14

5. Finally, add the remaining term: 16 + (-14) = 16 - 14 = 2

Therefore, the value of the expression 16 + (-6 - (18 + (4 - 9) - 2) + 1) is 2.
