What is 43 × 2?

Answer

43 × 2 =
86

43 × 2 and 2 × 43 are the same product — the order of the factors never changes the answer, only the working. Below, 43 is multiplied by 2 in a column, digit by digit.

43 × 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.

43 × 2 = 86

Step-by-Step Solution

Step 1: Multiply the multiplicand by the last digit of the multiplier, 2: 43 × 2 = 86.

  • 3 × 2 = 6. Write 6.
  • 4 × 2 = 8. Write 8.

86

Check It, and What It Is Not

Check by dividing back. Multiplication and division undo each other, so 86 ÷ 2 = 43 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.

43 × 2 is a number, not an area. If those are the sides of a room in feet, the answer is 86 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 43 × 2? (The answer is: 86). Enter the multiplicand (e.g. '43') and the multiplier (e.g. '2') and hit the button. The order of the two numbers does not matter — 43 × 2 and 2 × 43 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.
