Lattice Multiplication Algorithm
Lattice Algorithm method is a fun way to multiply two numbers. Let us have
fun using this method.
4 6
1. Multiply 46 × 54.
5
Draw 2 × 2 squares. Divide each square diagonally as
shown alongside. Write multiplicand, say 46, on the 4
top and multiplier, say 54, on the right side of the
squares. 4 6
2 3 5
Now, multiply 6 by 5 and write the product as shown.
0 0
Similarly, multiply other numbers and then add
diagonally. 1 2 4
6 4
Thus, 46 × 54 = 2484
2 4 8 4
2. Multiply 439 by 83.
To multiply 439 × 83, let us draw 3 × 2 squares. Divide each square
diagonally. Write the multiplicand and multiplier as shown alongside. Now,
do the process as earlier.
4 3 9
Thus, 439 × 83 = 36437 3 2 1 7 1 8
2 4 2
Now, using this method, multiply the following:
1 0 2 3
1. 68 × 47 2 9 7
2. 568 × 79
3 6 4 3 7
3. 356 × 428
