What is 50 × 30?

Answer

50 × 30 = 1,500

50 × 30 and 30 × 50 are the same product — the order of the factors never changes the answer, only the working. Below, 50 is multiplied by 30 in a column, digit by digit.

50 × 30 in a Column

The multiplicand goes on top, the multiplier underneath, both aligned on the right. Only one digit of the multiplier is not zero, and it stands for 30, so there is a single partial product and the answer goes straight under the line.

50 × 30 = 1,500

Step-by-Step Solution

Step 1: The last digit of the multiplier is 0, so this partial product is 0 and adds nothing to the total.

Step 2: The next digit of the multiplier is 3, and it stands for 30: 50 × 30 = 1,500.

  • 0 × 3 = 0. Write 0.
  • 5 × 3 = 15. Write 5 and carry 1.
  • No digits are left, so the carried 1 is written in front: the partial product is 150.

Check It, and What It Is Not

Check by dividing back. Multiplication and division undo each other, so 1,500 ÷ 30 = 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 × 30 is a number, not an area. If those are the sides of a room in feet, the answer is 1,500 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 × 30? (The answer is: 1,500). Enter the multiplicand (e.g. '50') and the multiplier (e.g. '30') and hit the button. The order of the two numbers does not matter — 50 × 30 and 30 × 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 × 30?

50 × 30 = 1,500

Is 50 × 30 the same as 30 × 50?

Yes. Multiplication is commutative, so both come to 1,500. Only the working differs: this page multiplies by 30, which gives a single partial product.

How do you check that 50 × 30 = 1,500?

Divide the product back by one of the factors: 1,500 ÷ 30 = 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 × 30?

Only one of them counts: every other digit of 30 is a zero and contributes nothing, so the work comes down to 50 × 30 = 1,500, with nothing left to add.
