Python the Calculator 🧮

Farmers, engineers and space scientists do a LOT of math. Python can do it in a blink.

print(5 + 3)
print(6 * 8)

💡

🧠 Dividing with / always gives a number with a dot, like 5.0.

🌽 Farm math

A farmer plants corn in rows. How many plants is that?

rows = 12
plants_per_row = 20
total = rows * plants_per_row
print("Corn plants:", total)

That shows Corn plants: 240. Imagine counting that by hand!

☀️ Solar power math

Solar panels turn sunlight into electricity, with no smoke and no pollution.

panels = 4
energy_per_panel = 3
print("Energy today:", panels * energy_per_panel)

Math with variables

You can change a box using its own value:

apples = 10
apples = apples + 5
print(apples)

That prints 15. Python works out the right side first (10 + 5), then puts the answer back into the box.

💧 Fun fact

Growing food uses a lot of water: farming uses roughly 70% of all the fresh water people take from rivers and lakes. That's why farmers use code and sensors to water plants only when they need it!
