Understanding Functions and Operators

This video tutorial covers the creation of various mathematical operators and functions in Snap, including the mod function, divisibility checks, even and odd number operators, and max/min operators. It also explains how to create and use libraries in Snap, and how to build a predicate to count the number of divisors of a number. The tutorial concludes with instructions on creating sum and list operations.

What does the mod function primarily calculate?

• The quotient of a division

• The sum of two numbers

• The remainder of a division

• The product of two numbers

If 16 is divided by 3, what is the remainder?

• 2

• 0

• 1

• 3

How can the mod function be useful in programming?

• For determining prime numbers

• For creating loops

• For sorting arrays

• For concatenating strings

What is the first step in creating a custom operator in Snap?

• Select the operators tab

• Select the motion tab

• Select the control tab

• Select the looks tab

What does the custom operator 'is divisible by' report?

• True or false based on divisibility

• The difference between two numbers

• The sum of two numbers

• The product of two numbers

What is the purpose of creating even and odd operators?

• To check if a number is prime

• To determine if a number is even or odd

• To find the square of a number

• To calculate the factorial of a number

What is a predicate in Snap?

• A block that reports true or false

• A type of variable

• A type of loop

• A block that performs arithmetic operations

How are libraries useful in Snap?

• They provide built-in sound effects

• They enable the reuse of blocks across projects

• They offer pre-made character sprites

• They allow for the creation of animations

What file format is used to export blocks in Snap?

• JSON

• XML

• CSV

• TXT

What does the 'number of divisors' predicate calculate?

• The smallest divisor of a number

• The count of divisors a number has

• The sum of all divisors

• The largest divisor of a number
