What is 670 × 9?

Answer

670 × 9 =
6,030

670 × 9 and 9 × 670 are the same product — the order of the factors never changes the answer, only the working. Below, 670 is multiplied by 9 in a column, digit by digit.

670 × 9 in a Column

The multiplicand goes on top, the multiplier underneath, both aligned on the right. The multiplier has a single digit, so there is one partial product and the answer goes straight under the line.

670 × 9 = 6,030

Step-by-Step Solution

Step 1: Multiply the multiplicand by the last digit of the multiplier, 9: 670 × 9 = 6,030.

  • 0 × 9 = 0. Write 0.
  • 7 × 9 = 63. Write 3 and carry 6.
  • 6 × 9 = 54, plus the carried 6 makes 60. Write 0 and carry 6.
  • No digits are left, so the carried 6 is written in front: the partial product is 6,030.

Check It, and What It Is Not

Check by dividing back. Multiplication and division undo each other, so 6,030 ÷ 9 = 670 must come out exactly, with no remainder.

Fractions are a different calculation. Both factors here are whole numbers; for 2/3 or 2 3/4 use the fraction multiplication calculator, which multiplies numerators and denominators separately.

670 × 9 is a number, not an area. If those are the sides of a room in feet, the answer is 6,030 square feet — the same arithmetic, a different question, and it is answered by the square footage calculator.

Long Multiplication Calculator

This calculator multiplies two whole numbers the way it is done on paper: digit by digit, carrying where the column overflows, then adding the partial products together. For example, it can help you find out what is 670 × 9? (The answer is: 6,030). Enter the multiplicand (e.g. '670') and the multiplier (e.g. '9') and hit the button. The order of the two numbers does not matter — 670 × 9 and 9 × 670 are the same product — so either number can go on top. Fractions and mixed numbers belong to the fraction multiplication calculator, and the reverse operation is long division.
