%X In primary school, some students find a difficulty in calculating a multiplication of two numbers. Moreover, students only familiar with certain method  to solve the problem. Actually, there are some methods that much easier to multiply numbers. In this paper, some of those techniques will be discussed, such as lattice multiplication, grid multiplication, and using reference number method. Those methods will be also explained from algebraic point of view.
Keywords: lattice multiplication, grid method, using reference number
