Quick revision
Remember these!
- Break large multiplication into place value parts.
- 234 x 23 = (234x3) + (234x20).
- 234 x 3 = 702, and 234 x 20 = 4,680.
- 702 + 4,680 = 5,382.
- This method works for any size number.
- Bigger numbers need more steps.
- Practice prepares us for real-world calculations.
- Checking answers helps avoid mistakes.
