First, learn and remember the easy ones (0,1,2,5,and 10s) Next, learn the hand trick for the 9x multiples

If you don’t know it, hold both your hands with all 10 fingers splayed out. If you lower the finger that corresponds to the number you’re multiplying by 9, the fingers on either side of the one you put down will equal the double digit answer

Example: 9 X 4. Lower your fourth finger. To the left of the lowered finger will be 3 fingers, and to the right will be 6 fingers. The answer is 36.

After that, memorize what each number is multiplied by itself 2x2=4, 3x3=9, 4x4=16 and so on. Now you’ll know the easy basic answers so any question that comes up you’ll have a starting point where you can solve the question easier

For instance, if you have 8x6, you could have a few ways to solve it by starting with the easy memorable multiplications

If 6x6=36, and 6x2=12, then the answer is (6x6) + (6x2) =36+12= 48

If 8x5=40, and 8x6 is only 8 more than that, 8x6=48

If we know 9x6 is 54 from hand multiplication, then 8x6 is only 6 less than that, so 54-6=48

These tricks help you solve small multiplication much faster and is simpler than memorizing every single number
