Multiplication of any two numbers, lies between 11 and 19

Maths Tricks , short cut tricks for maths to make calculation easy and fast

Multiplication of any two numbers, lies between 11 and 19 Let me explain this rule by taking examples 13*19 = (13+9)*10 + (3*9) = 220 + 27 = 247 Means add first number and last digit of the second number take zero in the third place of this number then add product of last digit of the two numbers in it.: Example.
18*14 = (18+4)*10 + (8*4) = 220 + 32 = 252; Is this maths trick helpful? (12724) (3763) Post / Read comment (45)

for numbers from 20 to 29 multiply with 20 instead of 10.
ex: 24*23= (24+3)*20 + (4*3) =552.
similarly for numbers from 30 to 39 multiply with 30 and so on.....
