I remember doing multiplication with decimals using lattice multiplication. It's not hard you just need to know how to move the decimal.

Side note, I remember in precalc in high school the teacher marked a student wrong on a test, for showing his work using lattice, because the teacher didn't understand it. The work was right, he showed his work, teacher just didn't know it so it was wrong. Man I hated that teacher.
