    155

    In the column: product 155.

    Step by step: 31 × 5

    1. Step 1Multiply the multiplicand by the last digit of the multiplier, 5: 31 × 5 = 155.
      • 1 × 5 = 5. Write 5.
      • 3 × 5 = 15. Write 5 and carry 1.
      • No digits are left, so the carried 1 is written in front: the partial product is 155.

    How do you check that 31 × 5 = 155?

    Divide the product back by one of the factors: 155 ÷ 5 = 31 exactly, with no remainder. Multiplication and division undo each other, which is what makes this check work.
