![]() He called one of the ways “latticemultiplication.” The name suggests thegratings that were placed in windows tokeep people from looking through them.1. Draw a diagonal through each box from the upper right corner to the lower-left corner. Draw a grid with \ (4\) columns and \ (3\) rows, depicting the multiplicand and multiplier as shown in the below. Luca Pacioli listed eight using the lattice method.different ways to do multiplication in thisbook. Lattice Multiplication Practice Problems 1. Using these rods to multiplyThe first printed arithmetic book appeared is almost the same asin Italy in 1478. Fifteenth-century The rods were strips ofwriters in western Europe included it in wood or bone, calledtheir printed books. The Arabians then passed multiply on to the Europeans. The lattice method of multiplication of numbered rodswas probably passed on from the Hindus that could be used toto the Arabians. Although the lattice multiplication strategy eliminates regrouping while solving the problem, it requires careful construction of the lattice (it needs to be. This technique usually begins with the construction of a lattice (. Operations and Computation ?Did You KnowThe search for ways to record computation In the late 1500s, Johnstarted in India, perhaps about the eleventh Napier invented a setcentury. Using the lattice method to multiply large numbers, requires just a very little technique. ![]() Then add 1 to the06 8 sum along the diagonal above. 02 4 84 26 Add the numbers along each diagonal starting at the right. ![]() 68 Write the answers as shown in the lattice. Write 34 on the right side of the lattice. 56 7 63 23 89 Add the 10s digit of 12 to the sum along the diagonal above. 89 The sum along one diagonal is 6 ϩ 6 ϭ 12. ◆ Write the 1s digit.◆ Add the 10s digit to the sum along the diagonal above.Use the lattice method. Operations and ComputationThe numbers along a diagonal may add up to a 2-digitnumber. 113 25 451 1 1 3 Add the numbers along each diagonal, 2 5 starting at the right. Write 3 on the right side of the lattice. 45 The box with squares and diagonals is called a lattice. Use the lattice method to multiply 3 ϫ 45. It is very easy to use if you know thebasic multiplication facts. They practice using this multiplication algorithm. Operations and ComputationLattice Multiplication MethodThe lattice method for multiplying numbers has been usedfor hundreds of years. Students review the lattice method for multiplication with 1- and 2-digit multipliers.
