Table Terminology:
There are 9 table Rows,
Row 1 through Row 9
Each Cell holds 3
numbers:
The Product (big number)
and its 2 Factors
For example,
this is Row 5:
5
Each Row has 10 Cells,
Cell 0 thru Cell 9.
For example,
this is Cell 6 in
Row 5.
Row, Cell, Factor, Product
6
In this Cell, the
Product is 30 and the
Factors are 5 and 6.
7 • 8=?
7 •8
Multiplying Two 1-digit Numbers
1. Find the Row
for the first Factor
In this case,
it’s Row 7:
3. The big number
above them is
their Product
56
2. Look across the
Row until you see
both Factors on
the bottom
In this case,
it’s 7 times 8
7 times 8
is 56
Ok, let’s try a few:
Click when you find the Product
77 •• 99=
99•• 44=
24
30
5 5•• 66=
63
36
33 •• 88=
Longer 1-Digit Multiplications: How to do “Carrying”
In this case, 4 is the multiplier.
Leave some space on the top.
We will use MrV’s Row 4:
4 • 582 = ?
If necessary, rewrite the numbers in
Vertical Format:

Use the shorter number as multiplier.
Neatness will improve accuracy.
23
8
3
2
4 x 8 is 32
Starting from the right,
4 x 2 is 8
(move the 8 to the product)
4 x 5 is 20, +3 is
(move the 2 to the product
and carry the 3 to over the 5)
23
(move the 23 to the product)
First, we’ll need Row 5: 5x7 then 5x7 then 5x5 then 5x9
Next, we’ll need Row 3: 3x7 then 3x7 then 3x5 then 3x9
Now, we’ll only need Row 7: 7x4 then 7x7 then 7x2
If you need to, use Rows 9 and 2 from MrV’s Multiplication Table
