**How To Use MrV’s Times Table For Multiplication**

Table Terminology Multiplying Two 1-Digit Numbers Longer 1-Digit Multiplications: How to do “Carrying” Multiplication by a 2-Digit Number Handling Trailing Zeroes in Multiplication Handling Internal Zeroes in Multiplication

**Table Terminology: Row, Cell, Factor, Product**

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 6 In this Cell, the Product is 30 and the Factors are 5 and 6. Each Row has 10 Cells, Cell 0 thru Cell 9. For example, this is Cell 6 in Row 5.

**7 • 8=? 56 Multiplying Two 1-digit Numbers**

7 • 8 1. Find the Row for the first Factor In this case, it’s Row 7: 3. The big number above them is their Product 7 times 8 is 56 56 2. Look across the Row until you see both Factors on the bottom In this case, it’s 7 times 8

4
**Ok, let’s try a few: Click when you find the Product**

7 • 9= 7 • 9 9 • 4= 24 9 • 4 30 5 • 6= 5 • 6 63 3 • 8= 3 • 8 36

**4 • 582 = ? 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. multiplicand ᵡ multiplier product Starting from the right, x 2 is 8 (move the 8 to the product) 4 x 8 is 32 (move the 2 to the product and carry the 3 to over the 5) 4 x 5 is 20, +3 is 23 (move the 23 to the product)

6
**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

7
**Now, we’ll only need Row 7: 7x4 then 7x7 then 7x2**

8
**If you need to, use Rows 9 and 2 from MrV’s Multiplication Table**
