selain perkalian unik, ada juga campuran antara perkalian dan penjumlahan yg unik……..

1.perkalian 8 dan penjumlahan urut……

( 1 x 8 ) + 1 = 9

( 12 x 8 ) + 2 = 98

( 123 x 8 ) + 3 = 987

( 1234 x 8 ) + 4 = 9.876

( 12345 x 8 ) + 5 =98.765

dan seterusnya……

2.hasil 8 dan kembarannya…….

(9 x 9) + 7 = 88

(9 x 98) + 6 = 888

(9 x 987) + 5 =8.888

(9 x 9.876) + 4 = 88.888

(9 x 98.765) + 3 = 888.888

dan seterusnya……

3. angka kembar berderet…….

22 x 22 = 121 x (1 + 2 + 1)

333 x 333 = 12.321 x (1+2+3+2+1)

4444 x 4444 = 1.234.321 x (1+2+3+4+3+2+1)

dan seterusnya…….

menyenangkan bukan matematika itu………
