Arrow-Puffin-3_Semester-1 Maths 159LATTICE MULTIPLICATIONThere is another method of multiplication called lattice multiplication, in which we use a lattice of squares. The numbers to be multiplied are written outside the lattice and the product is written inside the lattice after drawing diagonal line inside the rectangle.Note: Diagonal is a line segment that joins the opposite vertices in a rectangle.Example 1 : Multiply 78 and 3.%u2022 Draw the rectangle and the diagonal as shown.%u2022 Write the numbers to be multiplied outside the lattice as shown.%u2022 Multiply 8 and 3. (3 %u00d7 8 = 24) Write 2 and 4 as shown.%u2022 Multiply 7 and 3. (3 %u00d7 7 = 21) Write 21 as shown.Now, add the numbers along the diagonals as shown. Therefore, 78 %u00d7 3 = 2342 27124 383 427124 38724 38738 Find the product by lattice multiplication.1.27828 x 7 2.59454 x 9 3.78777 x 8Let's Understand Conceptual Understanding Let's Practise 4.10 Application
