What is 13 × 6?

Answer

13 × 6 =
78

13 × 6 and 6 × 13 are the same product — the order of the factors never changes the answer, only the working. Below, 13 is multiplied by 6 in a column, digit by digit.

13 × 6 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, 6: 13 × 6 = 78.

  • 3 × 6 = 18. Write 8 and carry 1.
  • 1 × 6 = 6, plus the carried 1 makes 7. Write 7.

Check It, and What It Is Not

Check by dividing back. Multiplication and division undo each other, so 78 ÷ 6 = 13 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.

13 × 6 is a number, not an area. If those are the sides of a room in feet, the answer is 78 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 13 × 6? (The answer is: 78). Enter the multiplicand (e.g. '13') and the multiplier (e.g. '6') and hit the button. The order of the two numbers does not matter — 13 × 6 and 6 × 13 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.

FAQ

What is 13 × 6?

13 × 6 = 78

Is 13 × 6 the same as 6 × 13?

Yes. Multiplication is commutative, so both come to 78. Only the working differs: this page multiplies by 6, which gives a single partial product.

How do you check that 13 × 6 = 78?

Divide the product back by one of the factors: 78 ÷ 6 = 13 exactly, with no remainder. Multiplication and division undo each other, which is what makes this check work.

What are the partial products of 13 × 6?

There is only one: the multiplier 6 has a single digit, so 13 × 6 = 78 is written straight under the line, with no addition step.
