PERKALIAN DUA DIGIT BELASAN CARA KESATU

12 * 13
= 1 ( 2 + 3 ) 2 * 3
= 1 5 6

14 * 12
= 1 ( 4 + 2 ) 4 * 2
= 1 6 8

13 * 15
= 1 ( 3 + 5 ) 3 * 5
= 1 8 15

= 1 ( 8 + 1 ) 5
= 195

14 * 13
= 1 ( 4 + 3 ) 4 * 3
= 1 7 12
= 1 ( 7 + 1 ) 2
= 1 8 2

12 * 17
= 1 ( 2 + 7 ) 2 * 7
= 1 9 14
= 1 ( 9 + 1 ) 4
= 1 10 4
= ( 1 + 1 ) 0 4
= 2 0 4

14 * 18
= 1 ( 4 + 8 ) 4 * 8
= 1 12 32
= ( 1 + 1 ) ( 2 + 3 ) 2
= 2 5 2
