Multiplying Larger Numbers

Multiplying Beyond Basic Facts

Sometimes you'll need to multiply bigger numbers, like two-digit by one-digit.

Steps to Multiply Larger Numbers

  1. Multiply the ones place first.
  2. Then multiply the tens place.
  3. Add the two results together.

Try breaking numbers apart to make it easier (using place value).

Practice Makes Perfect

Use paper, grids, or number lines if the numbers feel big!

Key Formula

\(23 \times 4 = (20 \times 4) + (3 \times 4) = 80 + 12 = 92\)

Examples

  • \(14 \times 3 = (10 \times 3) + (4 \times 3) = 30 + 12 = 42\)

  • \(27 \times 2 = (20 \times 2) + (7 \times 2) = 40 + 14 = 54\)

In a Nutshell

Multiply larger numbers by breaking them into parts and adding the results.
