| Multiply the
3 and the 2
and put the answer right under the
6: |
 |
Here's the third step...
This is the subtraction step!
Do the subtraction...
That's 6
- 6
= 0 |

Hey, we just finished the
first chunk of steps! And it wasn't that bad!
Division, then multiplication, then
subtraction.
Let's call it the DMS
loop!
Hey, those letters go
alphabetically!! You can use that to remember it!
OK, now we're going to do the
exact same thing, but with a different number...
First thing:
Drag the 8 down. |
 |
Now, let's go back into our
division, multiplication, subtraction loop using the 8!
| Division:
We want to see how
many times 2 will go into
8... 2
goes into 8 four
times... So, we put that 4
right above the 8: |
 |
| Multiplication:
Multiply the 4
and the 2 and put the
answer right under the
8: |
 |
| Subtraction:
That's 8
- 8
= 0 |
 |
Guess what? We are
DONE! (No way.) WAY!
We used the 6 and the 8...
and we ended with a 0
at the bottom...
Which I made into a "happy
face" because I was so
happy to be done!The
answer is 34. |
 |
So, we do our
DMS loop (division-multiplication-subtraction) until we use all the numbers in the
guy we are dividing into (that guy is officially called the dividend).
We have two ways to check
whether our answer is right or not:
| 1) |
Grab a calculator and do
68
divided by 2. |
| 2) |
Use multiplication!
Remember that division and multiplication go together...
They undo each other! So, 34
x 2
should = 68!
This is great practice for you. |
