Here are some Examples of Multiplication of two digit number with another two digit number tricks.
Example 1:- 12 x 15 ?
Step 1: Do Multiply 2 with 5 (2 x 5 = 10) Note down 0 and carry 1.
Step 2: Do cross Multiplication of 2 x 1 = 2 and 5 x 1 = 5.
Step 3: Add both results with carry 1 (step 1) so 2+5+1=8.
Step 4: Multiply both left side numbers i.e 1 x 1 = 1
Step 5: So finally we get result 180.
Example 2: 68 x 57 ?
Step 1: Do Multiply 8 with 7 (8 x 7 = 56) Note down 6 and carry 5.
Step 2: Do cross Multiplication of 6 x 7 = 42 and 8 x 5 = 40.
Step 3: Add both results with carry 5 (Step 1) so we get 40+42+5=87, Note down 7 and carry 8.
Step 4: Multiply both left side numbers i.e 6 x 5 = 30 and add carry(step 3) i.e 30+8=38.
Step 5: So finally we get result 3876.
