Should I state the formula before I start calculating, even when the math is simple?
- Case Math
When the math is easy, I tend to just calculate and give the number. Some coaches tell me to always state the formula first, even for basic percentage questions. Does saying the setup every time help, or can it make a simple calculation feel overexplained?
