Maths Problem Explanation

Problem: 47.03 + 1.97 equals _

My Explanation/Strategy:

1. I split the two numbers and add them. So I add 47 and 1 which equals 48. 
2. Then I add the two decimals which are .03 and .97. That will equal 1. 
3. I then add the 48 and the 1 which is 49, therefor the answer is 49. 

The Strategy I used was tidy numbers.
