Bilang mengikut gandaan = Count in multiples We can build a times table by skip counting. The table of 4 goes up by 4 each time: 4, 8, 12, 16, 20. The position tells you what to multiply by, so the third number, 12, is 3 × 4. Example: The table of 3: 3, 6, 9, 12, 15. The fifth number is 15 = 5 × 3. Watch out: Add the same amount at every step; skipping one number makes the rest wrong.
Fakta yang diketahui = Known facts A fact you already know can help with a new one. If 5 × 6 = 30, then 6 × 5 is also 30 because swapping the numbers keeps the product the same. This means you only need to learn about half of the times tables. Example: Knowing 2 × 9 = 18 tells you that 9 × 2 = 18. Watch out: This swapping trick works for multiplication, but not for subtraction.

Pola jawapan = Answer pattern In a times table, each answer grows by the same amount. The table of 7 grows by 7: 7, 14, 21, 28. If you forget 5 × 7, start from 4 × 7 = 28 and add 7 to get 35. Example: The table of 9: 9, 18, 27, 36. Each step adds 9, so 5 × 9 = 36 + 9 = 45. Watch out: When you use the pattern, start from a correct earlier answer.

Sifir darab = Times table The question asks for 7 × 2, which means seven groups of two. It is easier to swap it to 2 × 7, which is 7 + 7. You can also skip count by twos seven times and see if you land on the same number. Example: 8 × 2 = 2 × 8 = 8 + 8 = 16. Watch out: Multiplying by 2 doubles the number; it does not just add 2 to it.

Hasil darab = Product 6 × 3 means six groups of three. You can count by threes six times, or swap it to 3 × 6 and work out 6 + 6 + 6: first 6 + 6 = 12, then add one more 6. Each way checks the other. Example: 4 × 3 = 3 × 4 = 4 + 4 + 4 = 12. Watch out: Count how many numbers you add; missing one leaves out a whole group.
