Addi on can be done using fi ngers. Let’s add 4 and 3 1 2 3
using fi ngers. 4
• Count the fi rst number on your fi ngers. So, count
4 fi ngers and fold the remaining fi ngers.
• Now, count the second number on the remaining 2 3 4 6 7
fi ngers. So, count 3 more fi ngers. 5
1
• The total number of fi ngers is the answer.
So, 4 + 3 = 7.
2. Check the addi on. Then put a ck ( ) if it is correct or a cross () if it
is incorrect.
