Mathematics Shortcut Tricks For Multiplication
Today Shortcuts Tricks are very
important to solve the matters. so we use here Mathematics Shortcut Tricks For Multiplication. In competition exams we have limited amount of time to solve
the question papers. so there we use the shortcut tricks to solve our
questions. If we don't use the shortcut tricks to solve the question papers
then we can't qualify the exams.
Here in this blog we use the
some Mathematics Shortcut Tricks which is very helpful to
qualify the competative exams. In Part - 1 we discuss about Addition Shortcut Tricks now in this Part - 2 we will discuss about Multiplication Mathematics Shortcut Tricks.2) MULTIPLICATION
a) Multiplication of two digits numbers
Example 1 :- 43 x 63 ?
Shortcut Trick
Step 1: Multiply 3 x 3 = 9. Note down 9 then,
Step 2 : Do Cross-multiplication (4 x 3 ) = 12 and (6 x 3 )= 18.
Step 3 : Add both the result (4 x 3 + 6 x 3) =30 and write down 0 to the left of 9 and carry 3.
Step 4 : Multiply Left hand side numbers ( 4 x 6 ) = 24 and add carry (24 + 3 ) = 27 and write down to the left of 0.
The Final Result is 2709.
Example 2 :- 13 x 13 ?
Shortcut Trick
Step 1: Multiply 3 x 3 = 9. Note down 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.
Step 4 : Multiply Left hand side numbers ( 1 x 1 ) = 1 and write down to the left of 6.
The Final Result is 169.
