Mathematical Intelligence

 

Mathematical Intelligence

We all require some numerical skills in our lives, whether it is to calculate our weekly shopping bill or to budget how to use our monthly income. Flexibility of thought and lateral thinking processes are a few skills which are needed in order to solve these problems. Mathematical intelligence generally represents your ability to reason and to calculate basic arithmetic computations. It also helps you to understand geometric shapes and manipulate equations. Mathematical intelligence is a strong indicator of general intelligence because many every day mental tasks require arithmetical operations even though numbers may not be involved.

KEGUANAAN PETAK SIFIR

KEGUNAAN PETA SIFIR
1. DARAB SATU DIGIT DENGAN SATU DIGIT

     CONTOH :   6 X 4

     a. Perhatikan petak di bawah.                    

1	2	3	4	5	6	7	8	9
2	4	6	8	10	12	14	16	18
3	6	9	12	15	18	21	24	27
4	8	12	16	20	24	28	32	36
5	10	15	20	25	30	35	40	45
6	12	18	24	30	36	42	48	54
7	14	21	28	35	42	49	56	63
8	16	24	32	40	48	56	64	72
9	18	27	36	45	54	63	72	81

     b. Tempat pertemuan sifir 6 (melintang) dan sifir 4 (menegak) adalah

         jawapannya ( 24 ).

2. MEMBAHAGI DENGAN NOMBOR SATU DIGIT BERBAKI

    CONTOH :    42    ÷   8   =

    a. Untuk mencari jawapannya, lihat petak sifir.       

1	2	3	4	5	6	7	8	9
2	4	6	8	10	12	14	16	18
3	6	9	12	15	18	21	24	27
4	8	12	16	20	24	28	32	36
5	10	15	20	25	30	35	40	45
6	12	18	24	30	36	42	48	54
7	14	21	28	35	42	49	56	63
8	16	24	32	40	48	56	64	72
9	18	27	36	45	54	63	72	81

b.     Lihat sifir 8 secara melintang. Cari nombor 42. Jika tiada, cari nombor

yang kurang daripada 42 iaitu 40. Lihat menegak di atas nombor 40,

iaitu nombor 5 . Ini bermakna

                                             5        baki     2

                           8          4    2

                                    -  4    0 

                                       0    2

3.    PERMUDAHKAN PECAHAN

       CONTOH :     8

                             16

a.     8 dan 16 ada di dalam sifir 8. ini membolehkan pecahan itu dibahagi

dengan sifir 8.

 

            Oleh itu,    8        ÷        8          =         1

                            16       ÷        8                     2

b.     Kita juga tidak perlu membahagi dengan lapan. Hanya perlu melihat

pada pecahan yang termudah sahaja (di bahagian tepi kiri sekali petak sifir).

1	2	3	4	5	6	7	8	9
2	4	6	8	10	12	14	16	18
3	6	9	12	15	18	21	24	27
4	8	12	16	20	24	28	32	36
5	10	15	20	25	30	35	40	45
6	12	18	24	30	36	42	48	54
7	14	21	28	35	42	49	56	63
8	16	24	32	40	48	56	64	72
9	18	27	36	45	54	63	72	81

c.      Jika sekiranya jawapan di bahagian kiri sekali bukan pecahan

termudah, kita boleh cari lagi di dalam petak sifir.

1	2	3	4	5	6	7	8	9
2	4	6	8	10	12	14	16	18
3	6	9	12	15	18	21	24	27
4	8	12	16	20	24	28	32	36
5	10	15	20	25	30	35	40	45
6	12	18	24	30	36	42	48	54
7	14	21	28	35	42	49	56	63
8	16	24	32	40	48	56	64	72
9	18	27	36	45	54	63	72	81

                                                                                            

2 4     dipermudahkan  menjadi     6   

3 2                                              8

Manakala    6     dipermudahkan lagi menjadi      3

                  8                                                    4
