1. Addition of Ten Digits Numbers
With the help of basic principles of tens and unit places, the addition of two- digit numbers is performed by
• Take 43+34
• Split the second number into tens and unit places. 34=30+4
• Finish the ten’s addition. 43+30=73
• Finally, add the remaining unit place digit. 73+4=77.
2. Tricks for Subtraction
Here is an example that requires a lot of borrowing
• Consider two numbers say 1000 and 676
• Subtract 1 from both the numbers, we get 999 and 675
• Then subtract 675 from 999, we get 234
• So, 1000 – 676 = 234.
