Example #1 – Multiplication of Two Digit Number

59 x 42 = ?
The result of multiplication of two digit number is 59 x 42 = 2478.
Step 1: Multiply (2 x 9 ) = 18 note down 8 and carry 1 then,
Step 2: Do Cross-multiplication (2 x 5) = 10 and (4 x 9) = 36.
Step 3: Add both the result with carry (10 + 36 + 1) = 47 and write down 7 carry 4.
Step 4: Multiply left hand side numbers (4 x 5) = 20 and add carry (20 + 4) write down to the left of 7
Finally the result we get 2478. (Try to calculate all four steps in mind).


Example #2 – Multiplication of Two Digit Number
13 x 13 = ?
The result of multiplication of two digit number is 13 x 13 = 169.
Step 1: Multiply 3 x 3 = 9 then,
Step 2: Do Cross-multiplication (1 x 3) = 3 and (1 x 3) = 3.
Step 3: Add both the result (1 x 3 + 1 x 3) = 6 and write down to the left of 9 (result of step 1).
Step 4: Multiply left hand side numbers (1 x 1) = 1 and write down to the left of 6 (result of step 3).
Finally the result we get 169. (Try to calculate all four steps in mind).


Example #3 – Multiplication of Two Digit Number
87 x 33 = ?
The result of multiplication of two digit number is 88 x 33 = 2871.
Step 1: Multiply (3 x 7) = 21 note down 1 and carry 2 then,
Step 2: Do Cross-multiplication (3 x 8) = 24 and (3 x 7) = 21.
Step 3: Add both the result with carry (24 + 21 + 2) = 47 and write down 7 carry 4.
Step 4: Multiply left hand side numbers (3 x 8) = 24 and add carry (24 + 4) write down to the left of 7
Finally the result we get 2871. (Try to calculate all four steps in mind).


Example #4 – Multiplication of Two Digit Number
38 x 27 = ?
The result of multiplication of two digit number is 38 x 27 = 1026.
Step 1: Multiply (7 x 8) = 56 note down 6 and carry 5 then,
Step 2: Do Cross-multiplication (7 x 3) = 21 and (2 x 8) = 16.
Step 3: Add both the result with carry (21 + 16 + 5) = 42 and write down 2 carry 4.
Step 4: Multiply left hand side numbers (2 x 3) = 6 and add carry (6 + 4) write down to the left of 2
Finally the result we get 1026. (Try to calculate all four steps in mind).


Example #5 – Multiplication of Two Digit Number
17 x 19 = ?
The result of multiplication of two digit number is 17 x 19 = 323.
Step 1: Multiply 7 x 9 = 63 (note down 3 and carry over 6).
Step 2: (1 x 9 + 1x 7 + 6 (add carry)) = 22 (note down 2 and carry over 2 for next step).
Step 3: (1 x 1 + 2) = 3, note it down.
And finally the result we get 323. (Try to calculate all three steps in mind).
