13 = 10+3.

i*q = 0

What's not very nice?

Well, you'll just have to learn them off by heart. Start with what you know, and work from there. Go in ascending order, from lowest to highest. Knowing the square of 13 (169) is also helpful.

13 times 1=13 because
1+3=4
4+9=13
13 times 2=26 because
3+6=9
9+15=26

take the number 4 add 2 every time you go to the next table
add this to 3 and add 4 to 9 every time you go to the next table
sorry if that's not any help
regards

Alternatively add 13 every time!

Just multiply by 65 instead and then divide by 5.

Every time?

i.e.

As these clearly give multiples of 13, I'm inclined to agree that they give multiples of 13.
