what is 1000 [?] 81 [?] 190 = 10
To find the missing operations represented by the question marks in the equation 1000 [?] 81 [?] 190 = 10, we need to work through it step by step.
Let's assume the first question mark represents addition (+) and the second question mark represents subtraction (-).
So the equation becomes: 1000 + 81 - 190 = 10.
To solve this, we start with the addition: 1000 + 81 = 1081.
Then we subtract: 1081 - 190 = 891.
Therefore, in this case, the missing operations represented by the question marks are addition (+) and subtraction (-), and the resulting value is 891.
