    What is 100 × 12?

    Answer

    100 × 12 =
    1,200

    2 partial products: 100 × 2 = 200 and 100 × 10 = 1,000. 12 × 100 gives the same 1,200.

    100 × 12 in a column

    100
    ×12
    200
    +1000
    1200

    In the column: product 1,200.

    Step by step: 100 × 12

    1. Step 1Multiply the multiplicand by the last digit of the multiplier, 2: 100 × 2 = 200.
      • 0 × 2 = 0. Write 0.
      • 0 × 2 = 0. Write 0.
      • 1 × 2 = 2. Write 2.
    2. Step 2The next digit of the multiplier is 1, and it stands for 10: 100 × 10 = 1,000.
      • 0 × 1 = 0. Write 0.
      • 0 × 1 = 0. Write 0.
      • 1 × 1 = 1. Write 1.
    3. Sum of the partial products200 + 1,000 = 1,200

    What is 100 × 12?

    100 × 12 = 1,200
