Hello I am learning different strategies to work out different problems

1. EA 423-377=46 
2.                  +3          +3                     426-380=46

This shows how to use equal additions.

1. Reverse 423-377=46 
2. 377___+3________+20______+23423 

This shows how to use reversibility.


I love learning new maths strategies.
