Values & variables · 8 minutes of curiosity

The snack shop.

An expression combines values to make a new value. Add, subtract, multiply, and divide with math blocks. Blocks nested inside other blocks are worked out first.

Your mission: arithmetic & expressions

Calculate 4 × 3 + 2 using math blocks, store the result in cookies, and print cookies.

▦ BLOCK LAB · made for making

Build it: choose a toolbox category, drag blocks onto the canvas, then snap instructions inside when I press Run. Drop values into matching sockets. Edit words or numbers directly on their blocks.

Inputs Try different values

Inputs give your program information. An “input” block reads a value by its exact name. Task checks use their own values.

From blocks to Python A bridge to your next adventure

Generate real Python from these blocks. The helper functions keep Bit’s messages familiar. Python has its own type rules; the Python trail explains them.

A little hint, please

Put a multiply block inside the left socket of an add block. This is how block nesting chooses the order.

How do I use these blocks?

Pick a category on the left to see its blocks. Drag a block onto the canvas. Instructions connect in a stack inside “when I press Run”. Rounded value blocks go into sockets. Change a field by selecting the word, number, or dropdown on the block.

Use the canvas zoom controls or Fit blocks if a stack goes out of view. Undo can bring back an accidental change. Disconnected blocks do not run. Your canvas saves here on this device.

Pack this idea for later: An expression has a value. Nesting makes the order of operations visible. Explore it in Python →
