What is 55 × 2?

Answer

55 × 2 =
110

55 × 2 and 2 × 55 are the same product — the order of the factors never changes the answer, only the working. Below, 55 is multiplied by 2 in a column, digit by digit.

55 × 2 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, 2: 55 × 2 = 110.

  • 5 × 2 = 10. Write 0 and carry 1.
  • 5 × 2 = 10, plus the carried 1 makes 11. Write 1 and carry 1.
  • No digits are left, so the carried 1 is written in front: the partial product is 110.

Check It, and What It Is Not

Check by dividing back. Multiplication and division undo each other, so 110 ÷ 2 = 55 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.

55 × 2 is a number, not an area. If those are the sides of a room in feet, the answer is 110 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 55 × 2? (The answer is: 110). Enter the multiplicand (e.g. '55') and the multiplier (e.g. '2') and hit the button. The order of the two numbers does not matter — 55 × 2 and 2 × 55 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.

Is 55 × 2 the same as 2 × 55?

Yes. Multiplication is commutative, so both come to 110. Only the working differs: this page multiplies by 2, which gives a single partial product.

How do you check that 55 × 2 = 110?

Divide the product back by one of the factors: 110 ÷ 2 = 55 exactly, with no remainder. Multiplication and division undo each other, which is what makes this check work.

What are the partial products of 55 × 2?

There is only one: the multiplier 2 has a single digit, so 55 × 2 = 110 is written straight under the line, with no addition step.
