Answer:
Explanation:
It has some of different different method to solve but this solution is very easy to understand..
E g:
Here, we will subtract “ 6 ”from both numbers and after that we will add the numbers.
7 – 6 + 7 – 6 = 1+1=2
8 –6 + 8 –6 =2+2=4
8 –6 +5 –6 =2–1=1
6 –6 +9 –6 =0+3=3
10 –6 +11 –6 =4+5=9
4 –6 +9 –6 =-2+3=1
hence , 4+9 = 1
i hope this is very simple method to get answer…
and you will get it
