Question

1/1-1/1-2^-1 +1/1+ 1/1+2^-1

Answer 1

1 / 1 − 1 / 1 − 2−1 + 1 / 1 + 1 / 1 + 2−1 = 2

Answer 2

Let's solve the expression step by step:

1/1 - 1/1 - 2^-1 + 1/1 + 1/1 + 2^-1

Step 1: Simplify the fractions: 1/1 - 1/1 = 0

Step 2: Simplify the exponent: 2^-1 = 1/2

Step 3: Combine the terms: 0 - 1/2 + 1/1 + 1/1 + 1/2

Step 4: Combine like terms: (0 + 1/1 + 1/1) - 1/2 + 1/2

Step 5: Simplify further: 1 + 1 - 1/2 + 1/2

Step 6: Combine like terms: (1 + 1) - (1/2 - 1/2)

Step 7: Simplify further: 2 - 0

Step 8: Final result: 2

So, the final result of the expression is 2.
