Missing Term

There are 2 ways to find the missing term.

METHOD 1:   Use math facts

6 + = 14

Think: 6 + 8 = 14

The missing term is 8.
6 + 8 = 14

METHOD 2:   Use inverse operations

- 11 = 10

Think: 10 + 11 = 21

The missing term is 21.
21 - 11 = 10

### Complexity=5

Supply the missing term.
 1.   5 = 9 - 2.   5 + = 7

### Complexity=5, Mode=algebra

Supply the missing term.
 1.   7 = n + 2 n = 2.   n - 4 = 1 n =
