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

2
There are 9 table Rows, Row 1 through Row 9 Each Row has 10 Cells, Cell 0 thru Cell 9. Each Cell holds 3 numbers: The Product (big number) and its 2 Factors Table Terminology: Row, Cell, Factor, Product For example, this is Row 5: For example, this is Cell 6 in Row 5. In this Cell, the Product is 30 and the Factors are 5 and

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

4
Ok, let’s try a few: Click when you find the Product 7 9= 5 6= 9 4= 3 8=

4 582 = ? If necessary, rewrite the numbers in Vertical Format: Use the shorter number as multiplier. Neatness will improve accuracy. 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: multiplicand multiplier product Starting from the right, 4 x 2 is 8 (move the 8 to the product) 4 x 8 is 3 2 (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
