Understanding the Product of 23 and 39: Which Choice Shows The Product Of 23 And 39
Multiplication is a fundamental arithmetic operation that involves finding the product of two or more numbers. In this case, we will focus on the product of 23 and 39.
To calculate 23 x 39, we can use the traditional long multiplication method:
- Multiply 39 by 3, the units digit of 23, and write the result (117) under 39.
- Multiply 39 by 2, the tens digit of 23, and write the result (780) above 117, but shifted one place to the left.
- Add the two partial products to get the final product: 117 + 780 = 897.
Therefore, the product of 23 and 39 is 897.
