What is 50 × 15?

Answer

50 × 15 = 750

50 × 15 and 15 × 50 are the same product — the order of the factors never changes the answer, only the working. Below, 50 is multiplied by 15 in a column, digit by digit.

50 × 15 in a Column

The multiplicand goes on top, the multiplier underneath, both aligned on the right. Each digit of the multiplier produces its own partial product, and the partial products are added up.

Step-by-Step Solution

Step 1: Multiply the multiplicand by the last digit of the multiplier, 5: 50 × 5 = 250.

  • 0 × 5 = 0. Write 0.
  • 5 × 5 = 25. Write 5 and carry 2.
  • No digits are left, so the carried 2 is written in front: the partial product is 250.

Step 2: The next digit of the multiplier is 1, and it stands for 10: 50 × 10 = 500.

  • 0 × 1 = 0. Write 0.
  • 5 × 1 = 5. Write 5.

250 + 500

=

750

Adding the partial products finishes the work: 50 × 15 = 750.

Check It, and What It Is Not

Check by dividing back. Multiplication and division undo each other, so 750 ÷ 15 = 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 × 15 is a number, not an area. If those are the sides of a room in feet, the answer is 750 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 × 15? (The answer is: 750). Enter the multiplicand (e.g. '50') and the multiplier (e.g. '15') and hit the button. The order of the two numbers does not matter — 50 × 15 and 15 × 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.
