Lesson One hundred eighty: MISSING SYMBOLS

We've looked at examples involving missing plus and minus signs. Now we take a look at some examples missing multiplication and division signs. 


        5 __ 5 = 25
You can quickly recognize that the missing symbol is a multiplication sign since the only way the answer could be 25 is to multiply the two fives.

Here are some more examples.

    -------------------+------------------------
      5 __ 2 = 10      |          x
      10 __ 2 = 5      |          ÷
      10 __ 2 = 20     |          x
      21 __ 3 = 7      |          ÷
      45 __ 15 = 3     |          ÷
      6 __ 7 = 42      |          x
                       |
