The only way to learn to multiply more easily is to know how to add well, this is how all multiplication is a sum, so it is possible to write any multiplication as a very simple sum.
Examples:
a) 3x2 = 6, because 3 times the 2 is added, or 2 times the 3 is added, that is: 3 + 3 = 6 or 2 + 2 + 2 = 6
b) 5x8 = 40, because 5 times the 8 is added, or 8 times the 5 is added, that is: 8 + 8 + 8 + 8 + 8 = 40 or 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 = 40
