What is 50 × 8?

Answer

50 × 8 = 400

50 × 8 and 8 × 50 are the same product — the order of the factors never changes the answer, only the working. Below, 50 is multiplied by 8 in a column, digit by digit.

50 × 8 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, 8: 50 × 8 = 400.

  • 0 × 8 = 0. Write 0.
  • 5 × 8 = 40. Write 0 and carry 4.
  • No digits are left, so the carried 4 is written in front: the partial product is 400.

Check It, and What It Is Not

Check by dividing back. Multiplication and division undo each other, so 400 ÷ 8 = 50 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.

50 × 8 is a number, not an area. If those are the sides of a room in feet, the answer is 400 square feet — the same arithmetic, a different question, and it is answered by the square footage calculator.

About "Long Multiplication Calculator" 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 50 × 8? (The answer is: 400). Enter the multiplicand (e.g. '50') and the multiplier (e.g. '8') and hit the button. The order of the two numbers does not matter — 50 × 8 and 8 × 50 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 50 × 8?

50 × 8 = 400

Is 50 × 8 the same as 8 × 50?

Yes. Multiplication is commutative, so both come to 400. Only the working differs: this page multiplies by 8, which gives a single partial product.

How do you check that 50 × 8 = 400?

Divide the product back by one of the factors: 400 ÷ 8 = 50 exactly, with no remainder. Multiplication and division undo each other, which is what makes this check work.

What are the partial products of 50 × 8?

There is only one: the multiplier 8 has a single digit, so 50 × 8 = 400 is written straight under the line, with no addition step.
