Try to calculate the result below cipher out attentively please: 13 X12 = ? (multiplicand) (multiplier) such the Indian calculating: The first pace: First (13) a digit that follows multiplier (2) add up

Try to calculate the result below cipher out attentively please:

13 X12 = ?

(multiplicand) (multiplier)

Such the Indian calculating:

The first pace: First (13) a digit that follows multiplier (2) add up

2 = of 13 + 15

The 2nd pace: Take the key of the first pace next with 10 (→ that is to say from the back add 0)

The 3rd pace: Again a digit multiplicand (3) multiply a digit with multiplier (2)

2 X3 = 6

(13 + 2) 6 = of X10 + 156

such, this is too magical really!

We try figure:

14 × 13:

(1) 14 + 3 = 17

(17 × of 2) 10 = 170

(4 × of 3) 3 = 12

(4) 170 + 12 = 182

 ———————————————————–

16 × 17:

(1) 16 + 7 = 23

(23 × of 2) 10 = 230

(6 × of 3) 7 = 42

(4) 230 + 42 = 272

 ———————————————————–

19 × 19

(1) 19 + 9 = 28

(28 × of 2) 10 = 280

(9 × of 3) 9 = 81

(4) 280 + 81 = 361

Very simple really, does everybody come around quickly let children learn?
