What is 450 × 5?

Answer

450 × 5 =
2,250

450 × 5 and 5 × 450 are the same product — the order of the factors never changes the answer, only the working. Below, 450 is multiplied by 5 in a column, digit by digit.

450 × 5 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.

450 × 5 = 2,250

Step-by-Step Solution

Step 1: Multiply the multiplicand by the last digit of the multiplier, 5: 450 × 5 = 2,250.

  • 0 × 5 = 0. Write 0.
  • 5 × 5 = 25. Write 5 and carry 2.
  • 4 × 5 = 20, plus the carried 2 makes 22. Write 2 and carry 2.
  • No digits are left, so the carried 2 is written in front: the partial product is 2,250.

Check It, and What It Is Not

Check by dividing back. Multiplication and division undo each other, so 2,250 ÷ 5 = 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 × 5 is a number, not an area. If those are the sides of a room in feet, the answer is 2,250 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 450 × 5? (The answer is: 2,250). Enter the multiplicand (e.g. '450') and the multiplier (e.g. '5') and hit the button. The order of the two numbers does not matter — 450 × 5 and 5 × 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.
