Long Multiplication: 16 × 4
What is 16 × 4?
Answer
16 × 4 and 4 × 16 are the same product — the order of the factors never changes the answer, only the working. Below, 16 is multiplied by 4 in a column, digit by digit.
16 × 4 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.
| 1 | 6 | |
| × | 4 | |
| 6 | 4 |
Step-by-Step Solution
Step 1: Multiply the multiplicand by the last digit of the multiplier, 4: 16 × 4 = 64.
- 6 × 4 = 24. Write 4 and carry 2.
- 1 × 4 = 4, plus the carried 2 makes 6. Write 6.
16 × 4
=64
Check It, and What It Is Not
Check by dividing back. Multiplication and division undo each other, so 64 ÷ 4 = 16 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.
16 × 4 is a number, not an area. If those are the sides of a room in feet, the answer is 64 square feet — the same arithmetic, a different question, and it is answered by the square footage calculator.
