Lattice Multiplication Step-by-Step

I don’t remember how to multiply!!! 356 * 25 = I don’t remember how to multiply!!!

I can help!! Let me show you how to do Lattice Multiplication.

356 * 25 Make a grid the exact size of your problem. A 2 digit number times a 3 digit number gets a 2 x 3 grid. Draw a diagonal line in each box. 5 3 6 2 5

Multiply 6 * 2 and place the answer in the grid where the lines meet. 356 * 25 Multiply 6 * 2 and place the answer in the grid where the lines meet. 5 3 6 1 2 2 5

Multiply 5 * 2 and place the answer in the grid where the lines meet. 356 * 25 Multiply 5 * 2 and place the answer in the grid where the lines meet. 5 3 6 1 1 2 2 5

356 * 25 Multiply 3 * 2 and place the answer in the grid where the lines meet. Use a zero as a place holder. 5 3 6 1 1 2 6 2 5

Multiply 6 * 5 and place the answer in the grid where the lines meet. 356 * 25 Multiply 6 * 5 and place the answer in the grid where the lines meet. 5 3 6 1 1 2 6 2 3 5

Multiply 5 * 5 and place the answer in the grid where the lines meet. 356 * 25 Multiply 5 * 5 and place the answer in the grid where the lines meet. 5 3 6 1 1 2 6 2 2 3 5 5

Multiply 3 * 5 and place the answer in the grid where the lines meet. 356 * 25 Multiply 3 * 5 and place the answer in the grid where the lines meet. 5 3 6 1 1 2 6 2 1 2 3 5 5 5

356 * 25 Now add the diagonals and place the answer below the grid. Be sure to carry to the next diagonal if you have a 2 digit answer. 5 3 6 1 1 2 6 2 1 2 3 5 5 5

356 * 25 Now add the diagonals and place the answer below the grid. Be sure to carry to the next diagonal if you have a 2 digit answer. 5 3 6 1 1 +1 2 6 2 1 2 3 5 5 5

356 * 25 Now add the diagonals and place the answer below the grid. Be sure to carry to the next diagonal if you have a 2 digit answer. 5 3 6 1 1 +1 2 6 2 1 2 3 5 5 5 9

356 * 25 Now add the diagonals and place the answer below the grid. Be sure to carry to the next diagonal if you have a 2 digit answer. 5 3 6 1 1 +1 2 6 2 1 2 3 5 8 5 5 9

356 * 25 Now add the diagonals and place the answer below the grid. Be sure to carry to the next diagonal if you have a 2 digit answer. 5 3 6 1 1 +1 2 6 2 1 2 3 5 8 5 5 9

That is Soooo Cool!!! Thanks! 356 * 25 = 8,900
