Now let’s have a look
on the table of seventeen.
Here is the table of
seventeen as given in textbooks etc.
17 x 01 = 017
17 x 02 = 034
17 x 03 = 051
17 x 04 = 068
17 x 05 = 085
17 x 06 = 102
17 x 07 = 119
17 x 08 = 136
17 x 09 = 153
17 x 10 = 170
Tip
1:
Simply Padding Zero at the End of the number then sum up the same number twice
with answer and answer of multiplying number five times to get the table of
seventeen.
17 x 01 = 017 = (01 x 10) + (01 x 5) + (01 x 2) = 010 +
05 + 02
17 x 02 = 034 = (02 x 10) + (02 x 5) + (02 x 2) = 020 +
10 + 04
17 x 03 = 051 = (03 x 10) + (03 x 5) + (03 x 2) = 030 +
15 + 06
17 x 04 = 068 = (04 x 10) + (04 x 5) + (04 x 2) = 040 +
20 + 08
17 x 05 = 085 = (05 x 10) + (05 x 5) + (05 x 2) = 050 +
25 + 10
17 x 06 = 102 = (06 x 10) + (06 x 5) + (06 x 2) = 060 +
30 + 12
17 x 07 = 119 = (07 x 10) + (07 x 5) + (07 x 2) = 070 +
35 + 14
17 x 08 = 136 = (08 x 10) + (08 x 5) + (08 x 2) = 080 +
40 + 16
17 x 09 = 153 = (09 x 10) + (09 x 5) + (09 x 2) = 090 +
45 + 18
17 x 10 = 170 = (10 x 10) + (10 x 5) + (10 x 2) = 100 +
50 + 20
Tip
2:
Simply Padding Zero at the End of the number and multiply it with two then subtracts
the same number three times with answer and get the table of seventeen.
17 x 01 = 017 = (01
x 10) x 2 - (01 x 3) = (010 x 2) - 03
17 x 02 = 034 = (02
x 10) x 2 - (02 x 3) = (020 x 2) - 06
17 x 03 = 051 = (03
x 10) x 2 - (03 x 3) = (030 x 2) - 09
17 x 04 = 068 = (04
x 10) x 2 - (04 x 3) = (040 x 2) - 12
17 x 05 = 085 = (05
x 10) x 2 - (05 x 3) = (050 x 2) - 15
17 x 06 = 102 = (06
x 10) x 2 - (06 x 3) = (060 x 2) - 18
17 x 07 = 119 = (07
x 10) x 2 - (07 x 3) = (070 x 2) - 21
17 x 08 = 136 = (08
x 10) x 2 - (08 x 3) = (080 x 2) - 24
17 x 09 = 153 = (09
x 10) x 2 - (09 x 3) = (090 x 2) - 27
17 x 10 = 170 = (10
x 10) x 2 - (10 x 3) = (100 x 2) - 30
Tip
3:
Justify the answers with help of sums of digits.
17 x 01 = 017 = 0 + 1 + 7 = 8
17 x 02 = 034 = 0 + 3 + 4 = 7
17 x 03 = 051 = 0 + 5 + 1 = 6
17 x 04 = 068 = 0 + 6 + 8 = 14 = 1 + 4 = 5
17 x 05 = 085 = 0 + 8 + 5 = 13 = 1 + 3 = 4
17 x 06 = 102 = 1 + 0 + 2 = 3
17 x 07 = 119 = 1 + 1 + 9 = 11 = 1 + 1 = 2
17 x 08 = 136 = 1 + 3 + 6 = 10 = 1 + 1 = 1
17 x 09 = 153 = 1 + 5 + 3 = 9
17 x 10 = 170 = 1 + 7 + 0 = 8
