If the result is a single digit, put a zero in the top triangle.įor example, the top left box represents 2 (from 23) times 4 (from 45), which equals 08, so write 08 in the box. Write the result inside the box, with the tens digit going in the upper triangle (above the diagonal) and the ones digit going in the lower triangle (below the diagonal). Now, for each box, multiply the digit at the top of the column by the digit at the end of the row. The line should start from the bottom right of each square and end at the top left.
Your lattice should look like this:ĭraw a diagonal line through each square. Write the second number, 45, along the right side of the grid, one digit beside each row. Write the first number, 23, along the top of the grid, one digit above each column. Step 1: Draw the Lattice Gridĭraw a \(2×2\) square grid for our example because we have two digits in both numbers.

The correct answer will fly to the right place. In the steps the user will multiply or add. The Lattice Multiplication app allows the user to solve a lattice multiplication problem step by step and animates all the steps. Fibonacci presented both the current standard long multiplication and also an originally Indian method called lattice multiplication, which is faster and more compact for working with larger numbers. Ancient Indians and Chinese originally invented some of the algorithms. In this groundbreaking book Fibonacci presented many algorithms for working with Arabic numerals.
The method was introduced to Europe in 1202 in Fibonacci's Liber Abaci. All the multiplications are done first and then the additions. A lattice (a grid) guides the calculation. Lattice multiplication is algorithmically equivalent to long multiplication. The user can solve random and custom multiplication problems with small and large numbers. The app is very easy to use and it has an intuitive interface with customizable colors and other settings. Solving lattice multiplication problems is also excellent times tables practice. This app can be used to teach and study the ancient lattice multiplication method.
