How do you know if you're getting the right nutrients or just eating a lot of sugar? Math isn’t just for the classroom—it can help you break down food labels, balance meals, and even plan a diet that keeps you healthy and energized! This cycle, you’ll become a Mathematical Nutritionist, using math to analyze what you eat and create a meal plan that fuels your body the right way. Let’s crunch the numbers—literally!

Numbers can be really cool and useful, but when you put them together, the magic happens. We will take a look at how numbers interact to create new ones through addition, subtraction, multiplication, division, and more. We’ll explore percents to read , example daily value % on nutrition labels. to understand how numbers compare and scale in real-world situations.
