Question

6 + 10 - 2 = 11 +
how to find the missing number

Answer 1

Are you looking for the number that when added up with 11 gives you (6+10-2)? If yes, 6+10-2=14 Then you subrtact 14-11, and you get 3
6+10-2=11+3

Answer 2

The missing number can be shown as the variable x.

6 + 10 - 2 = 11 + x

So, you need to figure out what x is by getting it by itself. First, combine everything on the left side of the equation.

16 - 2 = 11 + x

14 = 11 + x

Now, what you do to one side of an equation, you have to do to the other. Subtract 11 from both sides

14 - 11 = 11 - 11 + x Cancel out the 11s and solve the left side.

3 = x

There's your answer! Now you can check your work by trying the 3 in your original problem.

6 + 10 - 2 = 11 + 3

14 = 14

Your missing number is 3.
