      • 0 × 3 = 0. Write 0.
      • 0 × 3 = 0. Write 0.
      • 4 × 3 = 12. Write 2 and carry 1.
      • No digits are left, so the carried 1 is written in front: the partial product is 1,200.

    FAQ

    What is 400 × 3?

    400 × 3 = 1,200

    Is 400 × 3 the same as 3 × 400?

    How do you check that 400 × 3 = 1,200?

    Divide the product back by one of the factors: 1,200 ÷ 3 = 400 exactly, with no remainder. Multiplication and division undo each other, which is what makes this check work.
