Question

1+1-(1+1)-1=? 1 или 2

Answer 1

1 + 1 - (1 + 1) - 1 = 2 - 2 - 1 = -1

Answer 2

Будет 1
1+1-(1+1)-1=1
1)1+1=2
2)1+1=2
3)2-2=0
4)0-1=1

Answer 3

When evaluating this expression, we follow the order of operations, which is typically remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

So, following PEMDAS, we first evaluate the expression inside the parentheses:

1+1-(1+1)-1 = 1+1-2-1

Next, we perform the subtraction and addition operations from left to right:

1+1-2-1 = 0

Therefore, the value of the expression 1+1-(1+1)-1 is 0, not 1 or 2.
