could you use doubling to multiply 7x3? explain.
Yes, you can use doubling to multiply 7x3. Doubling is a method where you start with a number and keep adding the number to itself repeatedly until you reach the desired result.
To use doubling to multiply 7x3, you can start with the number 3 and double it successively. Here's how it would look:
1. Start with the number 3.
2. Double 3 to get 6.
3. Double 6 to get 12.
4. Since 12 is greater than 7, we need to subtract the excess. In this case, we subtract 7 from 12, which leaves us with 5.
5. Double 5 to get 10.
6. We still need to add the remaining value of 2 (7 - 5 = 2). So, we add 2 to 10, which gives us the final result of 12.
So, by doubling the number 3 and handling any excess values, we can find that 7 multiplied by 3 equals 12.
