To find the product of 81 and 3, we multiply the two numbers together.
First, break it down: 81 x 3
Multiplying 81 by 3, we can think of it as adding 81 three times:
- 81 + 81 + 81
When we do this addition:
- 81 + 81 equals 162
- 162 + 81 equals 243
So, 81 x 3 = 243.
In conclusion, the answer is 243. This method not only helps in understanding multiplication, but also shows how addition is closely related to it.
