Trick to remember the table of 19.

Since it is
easy to remember the table of 20. So you can obtain the table of 19 from table
of 20.

To get table
of 19 just minus the number from 20’s table for e.g. if you want to get value of
19 × 5 just minus the 5 from 20 × 5

19×5 = (20 ×
5) -5 = 95.

20 × 1 = 20 19 ×1 = (20-1) = 19

20 × 2 = 40 19 × 2 = (40-2) = 38

20 × 3 = 60 19 × 3 = (60-3) = 57

20 × 4 = 80 19 × 4 = (80-4) = 76

20 × 5 = 100
19 × 5 = (100-5) = 95

20 × 6 = 120 19 ×6 = (120-6) = 114

20 × 7 = 140 19 ×7
= (140-7) = 133

20 × 8 = 120 19 ×8 =(160-8) = 152

20 × 9 = 180 19 ×9 = (180-9) = 171

20 × 10 = 200 19 ×10 = (200-10) = 200

This trick
can be further extended to 199,299,399 …… 1999.

Nice Trick! Here is another one: simple trick for writing multiplication table of numbers ending in 9

ReplyDeletewhats the trick in that ?

ReplyDeletethese rules are valid for tables of all the numbers ...

18 X 1 = 18 and 19 X 1 = (18 X 1)+1

18 X 2 = 36 and 19 X 2 = (18 X 2)+2

18 X 3 = 54 and 19 X 3 = (18 X 3)+3

.

. and so on.
