Multiple Choice

It's the pillar that consists in breaking down a large problem into smaller tasks

• Algorithms

• Decomposition

• Patterns

• Abstraction

Multiple Choice

A sequence of instructions that can be followed to solve many problems of similar type.

• Algorithms

• Decomposition

• Patterns

• Abstraction

Multiple Choice

Method of problem solving that aims for analysis and efficiency.

• Electronical Thinking

• Computational Thinking

• Intelligent Thinking

Multiple Choice

It's the coding language we'll learn in this class, it's one of the easiest ones to learn

• Java

• HTML

• Python

• C++

Multiple Choice

Algorithms are a series of steps that help solve a task, but they don't solve the task by themselves.

• True

• False

Multiple Choice

It's the information an algorithm requires in order to be able to function

• Finite

• Input

• Output

• Effective

Multiple Choice

Which one is NOT a property of Algorithms?

• Short

• Effective

• Finite

• Input

Multiple Choice

Property of Algorithms that dictates that they must always have an end.

• Output

• Effective

• Finite

• Precise and General

Multiple Choice

It's the name of ANY information that comes out of the device.

• Output

• Input

• Process

Multiple Choice

This happens inside the device without any control from us.

• Output

• Input

• Process

Multiple Choice

In a physical context, a computer's Keyboard is considered...

• Input

• Output

• Both

Multiple Choice

Pillar that finds similar information that repeats on a problem.

• Algorithms

• Decomposition

• Patterns

• Abstraction

Multiple Choice

In a calculator, the numbers and operators serve as the Inputs

• True

• False

Multiple Choice

Pillar that hides the information we don't need so we focus on what matters at the moment.

• Algorithms

• Decomposition

• Patterns

• Abstraction

Multiple Choice

It's the correct way to express an exponent in coding

• x

• *

• **

• ^

Multiple Choice

The camera on a phone is an Output

• True

• False

Multiple Choice

It's the operator that returns the REMAINDER of a division

• /

• //

• &

• %

Multiple Choice

A touchscreen can be considered...

• Input

• Output

• Both

Multiple Choice

In an Integer Division, the result is always rounded DOWN

• True

• False

Multiple Choice

Symbol that means "Lesser than or equal to"

• >

• <

• >=

• <=

Multiple Choice

Operator that is a normal division, but will always be rounded down

• /

• %

• //

• &

Multiple Choice

In PEMDAS, which of these operators has the highest priority?

• /

• %

• +

• **

Multiple Choice

Evaluate this expression: 6 >= 6

• True

• False

Multiple Choice

In PEMDAS, which of these operators has the highest priority?

• ( )

• *

• //

• -

Multiple Choice

Operator that checks if two values are the SAME

• =

• ==

• !=

% // / and * all have the SAME PRIORITY, they'll be solved left to right in whatever order they come. Same goes of + and -

Remember!

Multiple Choice

Evaluate this: (5+2)*2 == 5+2*2

• True

• False

Multiple Choice

Evaluate this: 13%6 <= 3

• True

• False

Multiple Choice

VERY HARD QUESTION: Evaluate (8-2*3 < 13) == (50/2 > 14%3)

• True

• False

Multiple Choice

Operator that checks if two values are DIFFERENT

• =

• ==

• !=

Multiple Choice

Evaluate this: (4+26)/2 != 4**2

• True

• False

Multiple Choice

It's a visual representation of an Algorithm

• Mindmap

• Flowchart

• Visual Map

• Instruction Chart

Multiple Choice

Shape used to represent a Decision in Flowcharts

• Oval

• Rhomboid

• Rectancle

• Diamond

Multiple Choice

Flowcharts can have multiple ending points

• True

• False

Multiple Choice

Shape used to represent the Start and Endings of a Flowchart

• Oval

• Rhomboid

• Rectangle

• Diamond

Multiple Choice

HARD QUESTION: Use PEMDAS and evaluate: (6%4+2)*2

• 0

• 6

• 8

• 2

Multiple Choice

Flowcharts can have multiple starting points.

• True

• False

Multiple Choice

Shape used to represent the INPUT and OUTPUT on Flowcharts

• Oval

• Rhomboid

• Rectangle

• Diamond

Multiple Choice

FINAL QUESTION: Which one is NOT a pillar of Computational Thinking

• Analysis

• Decomposition

• Abstraction

• Patterns

Poll

What topic(s) do you feel you need reviewing the most?

Remember you can also ask for tutoring :)

(If it's pillars tell me because I could only have 5 options)

• All good :)

• Algorithms

• Input Process Output

• Operators

• Flowcharts
