Question

Multiply using lattice method 1 ] 42x3. 2] 39x8 3.] 56x16. ​

Answer 1

$\large\underline{\sf{Solution-1}}$

$\rm \: 42 \times 3$

So, using lattice method [ See the attachment ]

$\rm\implies \:\boxed{ \rm{ \:42 \times 3 = 126 \: }}$

$\large\underline{\sf{Solution-2}}$

$\rm \: 39 \times 8$

So, using lattice method, [ See the attachment ]

$\rm\implies \:\boxed{ \rm{ \:39 \times 8 = 312 \: }}$

$\large\underline{\sf{Solution-3}}$

$\rm \: 43 \times 23$

So, using lattice method, [ See the attachment ]

$\rm\implies \:\boxed{ \rm{ \:43 \times 23 = 989 \: }}$

$\large\underline{\sf{Solution-4}}$

$\rm \: 56 \times 16$

So, using lattice method, [ See the attachment ]

$\rm\implies \:\boxed{ \rm{ \:56 \times 16 = 896 \: }}$

$\rule{190pt}{2pt}$

Basic Concept Used :-

The lattice multiplication involves 4 steps :-

1. Drawing the lattice.

2. Labelling the lattice with the digits.

3. Multiply the digits and fill the boxes of lattice.

4. Adding the digits diagonally.
