Mental tricks for addition

 Hey guys here are some simple tricks for addition....

1) Break big numbers into tens and units and then add the units and add the tens. 

For example - 14 + 5

2) Number 10 

    when a number is close to ten we can borrow number from the other or give the number to other to make it 10. It makes easy for the calculation.

For example - 8 + 6

3) Adding by using tables

   We can also add by using tables like-

1) 6 + 7 = 6 * 2 ( 6 + 6) + 1 = 13

2) 7 + 8

3) 8 + 9 etc.
