Berikut ini adalah beberapa Fakta Unik Matematika yang mungkin belum anda ketahui.
Perkalian dengan angka 1
1 x 1 = 1
11x 11 = 121
111 x 111 = 12321
1111 x 1111 = 1234321
11111 x 11111 = 123454321
111111 x 111111 = 12345654321
1111111 x 1111111 = 1234567654321
11111111 x 11111111 = 1213456787654321
111111111 x 111111111 = 12345678987654321
Hasilnya tetap 100
123 - 45-67 + 89 = 100
123 + 4 - 5 + 67-89 = 100
123-4 - 5 - 6 - 7 + 8 - 9 = 100
1 + 23-4 + 5 + 6 + 78-9 = 100
Perkalian 9,
1 x 9 = 09
2 x 9 =18
3 x 9 =27
4 x 9 =36
5 x 9 =45
6 x 9 =54
7 x 9 =63
8 x 9 =72
9 x 9 =81
1 x 9 + 2 = 11
12 x 9 + 3 = 111
123 x 9 + 4 = 1111
1234 x 9 + 5 = 11111
12345 x 9 + 6 = 111111
123456 x 9 + 7 = 1111111
1234567 x 9 + 8 = 11111111
12345678 x 9 + 9 = 111111111
123456789 x 9 + 10 = 1111111111
Angka yang dikalikan ditambah 1 ruas angka -1 di belakangnya, maka hasilnya adalah hasil sebelumnya + 1 ruas angka 8 di belakangnya
9 x 9 + 7 = 88
98 x 9 + 6 = 888
987 x 9 + 5 = 8888
9876 x 9 + 4 = 88888
98765 x 9 + 3 = 888888
987654 x 9 + 2 = 8888888
9876543 x 9 + 1 = 88888888
98765432 x 9 + 0 = 888888888
1 x 8 + 1 = 9
12 x 8 + 2 = 98
123 x 8 + 3 = 987
1234 x 8 + 4 =9876
12345 x 8 + 5 = 98765
123456 x 8 + 6 = 987654
1234567 x 8 + 7 = 9876543
12345678 x 8 + 8 = 98765432
123456789 x 8 + 9 = 987654321
9 x 1 = 09 ------------ 0 + 9 = 9
9 x 2 = 18 ------------- 1 + 8 = 9
9 x 3 = 27 ------------- 2 + 7 = 9
9 x 4 = 36 ------------- 3 + 6 = 9
9 x 5 = 45 ------------- 4 + 5 = 9
9 x 6 = 54 ------------- 5 + 4 = 9
9 x 7 = 63 ------------- 6 + 3 = 9
9 x 8 = 72 ------------- 7 + 2 = 9
9 x 9 = 81 ------------- 8 + 1 = 9
