2 Method 1 carry 1  8 4 8 1 7 2 8

last digit or unit value = 2, = 4, = 8

Multiple 2 only middle value

4*2 =8

8+4=12  write only 2 and 1 is carry and add in next value

1+2+4=7

Explain

Step 1. Select the last number or unit place of the value

in case unit place or last number of 12  is 2

Step 2.

write the unit place in this way

first time write unit place simple =  2

2nd time squarer the unit place = 4

3rd time cube root of unit place = 8

Step 3

now always multiple by 2 for middle 2 digits shoe in calculation

2*2 = 4

4*2 = 8

Step 4

Add the number show in calculation

Not we are used carry word meaning that

4+8 = 12 so write the only 2 and 1 is carry

Question 1 5 carry 6 carry 1  64 8 32 2 7 5 4 4

Final result = 2744

in 3rd column  solve

6+16+32=  54

6+6+2 = 14  write only 4 and one carry

1+1+3=5 Question

 3 18 34 1  343 14 98 4 9 1 3

Ans 4913

Step 1  select in 343 = 3 and carry 34

Step 2 Now 34+49+98=

4+9+8=21  and now write 1 and carry 2

2+3+4+9=18 carry and add in next value.

Step3   Now 18+7+14 =

8+7+4=19  carry 1

1+1+1=3  carry add in next value

Step 4

3+1=4
