What is 120 × 3?

Answer

120 × 3 =
360

120 × 3 and 3 × 120 are the same product — the order of the factors never changes the answer, only the working. Below, 120 is multiplied by 3 in a column, digit by digit.

120 × 3 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, 3: 120 × 3 = 360.

  • 0 × 3 = 0. Write 0.
  • 2 × 3 = 6. Write 6.
  • 1 × 3 = 3. Write 3.

Check It, and What It Is Not

Check by dividing back. Multiplication and division undo each other, so 360 ÷ 3 = 120 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.

120 × 3 is a number, not an area. If those are the sides of a room in feet, the answer is 360 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 120 × 3? (The answer is: 360). Enter the multiplicand (e.g. '120') and the multiplier (e.g. '3') and hit the button. The order of the two numbers does not matter — 120 × 3 and 3 × 120 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 120 × 3?

120 × 3 = 360

Is 120 × 3 the same as 3 × 120?

Yes. Multiplication is commutative, so both come to 360. Only the working differs: this page multiplies by 3, which gives a single partial product.

How do you check that 120 × 3 = 360?

Divide the product back by one of the factors: 360 ÷ 3 = 120 exactly, with no remainder. Multiplication and division undo each other, which is what makes this check work.

What are the partial products of 120 × 3?

There is only one: the multiplier 3 has a single digit, so 120 × 3 = 360 is written straight under the line, with no addition step.
