Discover the power of mathematical and logical blocks in Scratch!

With these blocks, you can perform basic arithmetic operations like addition, subtraction, multiplication, and division. Combine them to create more complex equations. For example, use them to pick a random number for a game feature or to compare values using greater than, less than, and equal blocks.

Explore the world of Boolean logic with blocks like "and," "or," and "not," which return true or false based on conditions. Use them to control when certain actions should occur, like repeating a task until a condition is met.

Join blocks allow you to combine words, variables, or equations into a single string of text. You can even use them to create a clock by stacking multiple join blocks together.

Other useful blocks include those for detecting specific letters or characters in text, performing modulo operations, rounding numbers, and manipulating mathematical functions like sine, cosine, and square root.
