Practise it, eventually it becomes easy and you can do them all without thinking.
Some are really easy too.
1 , 2 , 5 , 10 , 9, 11. these are really easy.
If you didn't know, 9 times table has a pattern
9 , 18 , 27 , 36
The tens column have +1
The units column have - 1
9, 18, 27, 36, 45, 54, 63, 72, 81, 90
As for 3s it gets easy if you practise and one you've perfected that the 4s are a walk in the park.+1
12 I just have a method but know I can do it without thinking 10+ & 2+
Both easy.
12 +10 + 2= 24
As long as that looks it's not once you think about it.
I had some trouble with 7s and a bit with 6.
Because they seemed a bit odd. But 6 is just 3*2 And 7 is 6+1.
But like I said practise, practise, practice...
Good luck..... ...!..!
