What is 450 × 8?

Answer

450 × 8 = 3,600

450 × 8 and 8 × 450 are the same product — the order of the factors never changes the answer, only the working. Below, 450 is multiplied by 8 in a column, digit by digit.

450 × 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: 450 × 8 = 3,600.

  • 0 × 8 = 0. Write 0.
  • 5 × 8 = 40. Write 0 and carry 4.
  • 4 × 8 = 32, plus the carried 4 makes 36. Write 6 and carry 3.
  • No digits are left, so the carried 3 is written in front: the partial product is 3,600.

Check It, and What It Is Not

Check by dividing back. Multiplication and division undo each other, so 3,600 ÷ 8 = 450 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.

450 × 8 is a number, not an area. If those are the sides of a room in feet, the answer is 3,600 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 450 × 8? (The answer is: 3,600). Enter the multiplicand (e.g. '450') and the multiplier (e.g. '8') and hit the button. The order of the two numbers does not matter — 450 × 8 and 8 × 450 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.
