68x4 eaqeuls 272.How I got it is you multiply the ones.Then you may have to regroup.Next I multiply diagnoly the tens.Thats how I get the answer.
First I multiplied 8 times 4 and got 32. So I put the 3 above the 6 and put 2 in the anser blank. Then I did 4 times 6 and got 24. Then aded the 3 and got 27. So I put 27 in the anser blank and got 272.
First you muliply the last two numbers,Then if there is a number in front that first number you carry it, Next you multiply the last bottom number with the top first number and add the number you carried and you get the awnser.
First I multiply the ones place and got 32.I cary the 3 to the tens place. I mulgiply the the tens place and got 24. I added the 3 to the 24 and got 27 so the sum is 272.
55 First I moltiply 5x5 and get x5 25 so I put the 2 above the ___ 5 and put the 5 down then 275 moltiply 5x5 and get 25 then add 2 and get 27 so put the 27 down befor the 5.
First you have to multiply 4x8=32. Next you put the 2 in the answer. Then you put the 3 above the 6. Fourth you multiply 4x6=24 and ad 24+3=27. Last you put 27 in the answer in front of 2 to get the answer 272.

When you regroup you multiply the bottom number.
First I multiplied 8 times 4 and got 32. So I put the 3 above the 6 and put 2 in the anser blank.
Then I did 4 times 6 and got 24. Then aded the 3 and got 27. So I put 27 in the anser blank and got 272.
The first thing you do is you multipli is the 8 and the 4 . Then you mulitiply the 6 and the 4 and it equls 272.
First you muliply the last two numbers,Then if there is a number in front that first number you carry it, Next you multiply the last bottom number with the top first number and add the number you carried and you get the awnser.
First you multaply the 8 to the 4. Then You carry the 3 on top of the 6. Next you add the 3 to the 6.Then you multaply the oblink numbers
First I multiply the ones place and got 32.I cary the 3 to the tens place. I mulgiply the the tens place and got 24. I added the 3 to the 24 and got 27 so the sum is 272.
68x4=272.How I got that is you multiply the ones .Then you might have to regroup the ones.Then you take the 4 and you times 8x4.
55 First I moltiply 5x5 and get
x5 25 so I put the 2 above the
___ 5 and put the 5 down then
275 moltiply 5x5 and get 25 then add 2 and get 27 so put the 27 down befor the 5.

First you have to multiply
4x8=32. Next you put the 2 in the answer. Then you put the 3 above the 6. Fourth you multiply 4x6=24 and ad 24+3=27. Last you put 27 in the answer in front of 2 to get the answer 272.
frist you multiply the ones.
then you may need to regroup.
next you multiply the tens.
68x4=272.
68 times 4=272 you need to regroup the 3 and leavre the 2 where it is.
