3-digit × 2-digit is nothing new — it reuses the 2-digit × 2-digit plan. First multiply by the ones digit for the first partial row; then multiply by the tens digit, whose ones must be written in the tens place — that is the "shift one place" step, because the tens digit counts tens. Add the two shifted rows and the column method is done.
Tap "Next" to walk through the column method: 234×56 first multiplies by the 6, then by the 50 with its ones ending at the tens place, then adds the shifted rows. The digit being multiplied lights up, carries are shown, from carry-free guided rounds to challenge rounds full of carrying.
