Tbh, I think the easiest way is to count on your fingers. I still do it, however I can now do my chart tables to 17x17 by using fingers.

Step-by-step explanation:
9x4
You can pretend that your thumb equals nine, and count 9 plus 9 plus 9 plus 9, with each other finger, such as your ring finger, pointer, middle, and pinky , which equals 36. 5x9, you have five fingers on each hand, so each finger can equal nine (I don't care if people say that your thumb isn't a finger, just take it and move on lol).
If Nico gave away some red circles and you would like to know how many red circles does he have left, you can calculate this using the following step:
Nico has 15 red circles.
n ... the number of red circles that he gave away
15 - n ... the number of circles that Nico still has
The correct result would be 15 - n.
