Answer 1

1) (11+11)+11*2=44
2) (11+11+11)/3=11       

Answer 2

1) 11 + 11 + 11 - 2 = 44 2) 11 - 11 + 11 - 3 = 11

To solve these equations, we need to fill in the missing arithmetic operation signs (?). Let's go through each equation step by step:

1) 11?11?11?2=44 To find the missing operation signs, we can start by looking at the equation from left to right. We see that there are three question marks in the equation. Let's fill them in one by one:

11?11?11?2=44 First question mark: 11?11?11?2=44 Since the left-hand side of the equation is 11 + 11 + 11, and the right-hand side is 44, we can conclude that the missing operation sign between the first two 11s is '+'.

11 + 11?11?2=44 Second question mark: 11 + 11?11?2=44 Now, we have 11 + 11 + 11 on the left-hand side and 44 on the right-hand side. This means that the missing operation sign between the second and third 11s is '+'.

11 + 11 + 11?2=44 Third question mark: 11 + 11 + 11?2=44 We have 11 + 11 + 11 on the left-hand side and 44 on the right-hand side. This implies that the missing operation sign between the third 11 and 2 is '-'.

11 + 11 + 11 - 2 = 44

So, the correct equation is 11 + 11 + 11 - 2 = 44.

2) 11?11?11?3=11 Similarly, let's find the missing operation signs in this equation:

11?11?11?3=11 First question mark: 11?11?11?3=11 Since the left-hand side of the equation is 11 - 11 + 11, and the right-hand side is 11, we can conclude that the missing operation sign between the first two 11s is '-'.

11 - 11?11?3=11 Second question mark: 11 - 11?11?3=11 Now, we have 11 - 11 + 11 on the left-hand side and 11 on the right-hand side. This means that the missing operation sign between the second and third 11s is '+'.

11 - 11 + 11?3=11 Third question mark: 11 - 11 + 11?3=11 We have 11 - 11 + 11 on the left-hand side and 11 on the right-hand side. This implies that the missing operation sign between the third 11 and 3 is '-'.

11 - 11 + 11 - 3 = 11

So, the correct equation is 11 - 11 + 11 - 3 = 11.
