__

 

+51

 

_________

 

96

 

 

 

Predict: I predict that I will need to do addition in this sum

 

Clarify: I have no words, sentences or phrases to clarify.

 

Find the big question: What are the missing digits?

 

Solve:

 

Well, 6+1 cant equal 6, so it has to equal 16.

6+1=7. 7+?=16? 9.

So we write down 9 and carry the one.

Now, 1+ the carried 1= 2. So, 2+5= 7, but 7+?=9? 2.

The answer is

 

16+29+51= 96.

 

Summary: The mathematicians toolbox strategy I used in this sum was break the problem into manageable parts, and use my prior knowlee.
