Example 4: Multiply 153 by 26.

Solution: Expand the multiplier 26 as 2 tens + 6 ones.
Step 1: Multiply 153 Step 2: Multiply 153 by Step 3: Add the products.
by 6 ones. 2 tens. 918 + 3060 = 3978

153 × 6 ones = 918 153 × 2 tens

= 153 × 20 ones = 3060 th H t O

lattice Multiplication

We can also multiply the numbers using the lattice multiplication.

Let us multiply 56 by 34 using this method.

Step 1: Since 56 and 34 are both 2-digit numbers, draw a 2 × 2 grid.

Also, draw diagonal lines in each box as shown.

Step 2: Write the multiplicand on top and the multiplier on the right of the grid as shown.
Step 3: Multiply the numbers and write the tens place digit in the 5 6
upper triangle of each box. Write the ones digit in the lower 1 1 8 3

triangle of each box. 5
2 2
0 4 4

Teacher’s Explain this with an example. If the answer is just one digit, write 0 in the top 4 0
Tip triangle to help with place value. Like: 2 8
