1.first you do the sum that you have been given.
234-143
2.next you write h t u and write your number below.
h t u
2 3 4
1 4 3
3.then you do a line below your numbers.
h t u
2 3 4
1 4 3
——-
4. you start to work out the answer by starting with u. so you do 4-3=1

h t u
2 3 4
1 4 3
—–
1
5.then you do 3 subtract 4 which is impossible. so we use 1 from the h and put it infront of the 3. so the sum for the t is 13-4=9.

h t u
2 3 4
1 4 3
——-
9 1
6. then you do the h and it is 1-1=0 because we took 1 earlier.
h t u
2 3 4
1 4 3
——-
0 9 1

a. 234 – 143=
1.First we have to write Hundreds,Ten and Unit.
2.Your next step is to write the 2,3 and 4 underneath the Hundreds,Ten and Unit column.
3.Then draw a line to split the sums and the answers so they do not get messed up.
4.Now you have to start from the units to get your answers right.
H T U
2 13 4
– 1 4 3
___________
1

5.So now you have to take away 4 from 3 which is 1.
6.Then you have to take away 3 from 4 you can’t do that so you have to exchange a ten from the hundreds column
which will make it easerier for us because now it will be 13-4.The answer would be 9.
7.There is going to be a 1-1=0
