Frequently Asked Questions
- What is lattice multiplication?
- A grid method: digits of one number go along the top, the other down the side; each cell holds the product of those digits; add along diagonals to get the final result.
- Why use lattice method?
- It organizes place values clearly and can be easier for some learners than the standard algorithm.
- Does it work with decimals?
- The same grid idea works; position the decimal point in the result by counting decimal places in the factors.
