MathToolsforNeuroscience Greg Ilana
Today: • Introduction • Equations are your friends • <break> • Remember Calculus?
The two questions: What am I going to learn? Math a foreign language: Why should I care? Because you will be tested on it.
Why Is Important for a Neuroscientist to Learn Math? To calculate stuff To prove stuff To understand to express, to describe, to communicate just like a language

What’s in an Equation, Really? It’s a statement.
What’s in an Equation, Really? It’s an ‘is’ statement. 17 - 3 5 = 2
