What is 49 × 9?

Answer

49 × 9 =
441

49 × 9 and 9 × 49 are the same product — the order of the factors never changes the answer, only the working. Below, 49 is multiplied by 9 in a column, digit by digit.

49 × 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.

Step-by-Step Solution

Step 1: Multiply the multiplicand by the last digit of the multiplier, 9: 49 × 9 = 441.

  • 9 × 9 = 81. Write 1 and carry 8.
  • 4 × 9 = 36, plus the carried 8 makes 44. Write 4 and carry 4.
  • No digits are left, so the carried 4 is written in front: the partial product is 441.

Check It, and What It Is Not

Check by dividing back. Multiplication and division undo each other, so 441 ÷ 9 = 49 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.

49 × 9 is a number, not an area. If those are the sides of a room in feet, the answer is 441 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 49 × 9? (The answer is: 441). Enter the multiplicand (e.g. '49') and the multiplier (e.g. '9') and hit the button. The order of the two numbers does not matter — 49 × 9 and 9 × 49 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.
