In Blockly, to calculate the factorial of a number n (n!), which Math block would you use in a loop?

Factorial is the product of numbers from 1 to n, using the Multiply block in a loop to multiply the numbers.

• Math 'Multiply' block

• Math 'Add' block

• Math 'Power' block

• Math 'Modulo' block

To check if a number is prime, which Logic block would be used to test for non-divisibility?

• 
• Logic 'AND' block with 'number > 1'

• Logic 'OR' block with 'number < 2'

• Logic 'Comparison' block with 'number = 1'

To create a program in Blockly to check if a year is a leap year, which Logic block would you use?

• 
• 
• 
• 

In Blockly, to calculate the sum of odd numbers from 1 to n, which Math and Logic blocks would you use?

• 
• 
• 
• 

To create a program in Blockly to check if a number is a power of 2, which Math block would be useful?

A number is a power of 2 if it can be repeatedly divided by 2 (using Modulo) until reaching 1 with no remainder.

• Math 'Modulo' block with 'Remainder of number ÷ 2 = 0'

• Math 'Power' block with '2^x'

• Math 'Square root' block

• Math 'Round' block

To check if a sequence of numbers is strictly increasing, which Logic block would you use in Blockly?

Compare each pair of consecutive elements (a[i] < a[i+1]) using the Comparison block to check for a strictly increasing sequence.

• Logic 'Comparison' block with '<' between consecutive elements

• Logic 'AND' block with 'number % 2 = 0'

• Logic 'OR' block with 'number > 0'

• Logic 'NOT' block with 'number = 0'

In Blockly, to calculate the absolute value of a complex expression (e.g., x - y), which block would you use?

• Math 'Absolute' block

• Math 'Round' block

• Math 'Modulo' block

• Math 'Power' block

To create a program in Blockly to check if three numbers form a Pythagorean triple (a² + b² = c²), which Math blocks would be used?

• Math 'Power' and 'Add' blocks

• Math 'Modulo' and 'Subtract' blocks

• Math 'Divide' and 'Round' blocks

• Math 'Square root' and 'Multiply' blocks
