5×161

5×161 refers to a multiplication problem. The operation involves multiplying the number 5 by the number 161.

The calculation of 5×161 can be performed using standard multiplication methods. One way to approach this is to break down 161 into its place values: 100, 60, and 1. Then, multiply each of these components by 5. So, 5 × 100 = 500, 5 × 60 = 300, and 5 × 1 = 5. Adding these results together gives 500 + 300 + 5 = 805.

Alternatively, standard vertical multiplication can be used. Write 161 above 5. Multiply 5 by the digit in the ones place of 161, which is 1. This gives 5. Write 5 in the ones place of the answer. Next, multiply 5 by the digit in the tens place of 161, which is 6. This gives 30. Write 0 in the tens place of the answer and carry over the 3 to the hundreds place. Finally, multiply 5 by the digit in the hundreds place of 161, which is 1, and add the carried-over 3. This gives 5 × 1 + 3 = 8. Write 8 in the hundreds place of the answer. The result of the multiplication is 805.

Therefore, 5×161 equals 805. This is a basic arithmetic operation with a single, definitive numerical answer.
