Answer:

1

Explanation:

This is simpler than what it appears, if you know the correct concepts of mathematics.

Apply the principle of BODMAS in this, explained as below:

B: Bracket

O: Of

D: Division

M: Multiplication

A: Addition

S: Subtraction.

The principle is to solve any problem in the order (hierarchy) of BODMAS, that is, solve ‘B’ before ‘O’ or ‘D’ before ‘S’.

In your question, there is no B and O. So go to D.

1/1 = 1

Then go to M.

The answer of the previous calculation is multiplied to 1.

1 x 1 = 1

Now, 1 + 1 = 2

Then, 2 - 1 (the solution of 1 x 1) = 1

So, the final solution is 1.

Answer:

1+1-1×1/ 1 = 9
