Adding Multiplying
1. Let's clarify the problem you are referring to about adding 2 and multiplying by 2.
2. Usually, adding 2 then multiplying by 2 means an operation like this: start with a number $x$, then compute $(x + 2) \times 2$.
3. The reason to add first is to increase the value by 2.
4. Then multiplying by 2 doubles the result, amplifying the final number.
5. For example, if $x = 3$, then first adding 2 gives $3 + 2 = 5$.
6. Next, multiplying by 2 gives $5 \times 2 = 10$.
7. The order of operations matters: if you multiplied by 2 first and then added 2, it would be $2 \times 3 + 2 = 8$, not 10.
8. This technique is common in math problems where you want to scale a shifted value.
9. So, "where it's me from" likely means where does this come from or why do we do both steps.
10. The answer is: adding 2 shifts the value, and multiplying by 2 scales it; doing both changes the original value in a controlled way.
Final summary: adding then multiplying changes a number $x$ to $(x + 2) \times 2$ to achieve a specific transformation of the number.
