This page focuses on solving one-step equations using inverse operations, a fundamental skill in algebra.
Key concepts covered:
Definition: Inverse operations are mathematical operations that undo each other, such as addition and subtraction or multiplication and division.
Example: For the equation x + 6 = 8, subtract 6 from both sides to isolate x: x = 8 - 6 = 2.
The page provides clear explanations and multiple examples to reinforce the concept of using inverse operations to solve equations.
This page introduces more complex multi-step equations and the balancing method for solving them.
Key points covered:
Vocabulary: The balancing method involves performing the same operation on both sides of an equation to maintain equality while isolating the variable.
Example: For the equation 7x + 4 = 25, first subtract 4 from both sides, then divide by 7 to get x = 3.
The page emphasizes the importance of working systematically and using inverse operations in the correct order to solve multi-step equations.
This page focuses on applying equation-solving skills to real-world scenarios and word problems.
Key concepts covered:
Example: A problem about upgrading airline seats is presented, where students must form and solve an equation to find the cost of a standard seat.
Highlight: The page stresses the importance of carefully reading word problems and identifying the key information needed to form equations.
This page delves deeper into perimeter calculations and provides additional practice with various types of equations.
Key points covered:
Definition: Perimeter is the total length around the edge of a shape.
Example: For a rectangle with length 6cm and width 4cm, the perimeter can be calculated as 2 = 20cm.
The page also includes a word problem about Noah's number, encouraging students to apply their equation-solving skills in a different context.
This page introduces parallelograms and explains how to calculate their areas.
Key concepts covered:
Vocabulary: A parallelogram is any quadrilateral with two pairs of parallel sides.
Highlight: The area of a parallelogram is calculated using the same formula as a rectangle: area = base × height.
The page emphasizes the importance of using the perpendicular height, not the slant height, when calculating the area of a parallelogram.
This final page introduces the concept of volume and its measurement.
Key points covered:
Definition: Volume is a measurement of the amount of space inside a 3D object.
Highlight: The page suggests that there are quicker ways to calculate volume than counting individual cubes, hinting at formulas to be learned in future lessons.
The page sets the foundation for more advanced volume calculations in future mathematics studies.
This page introduces fundamental concepts of percentages and basic equation solving.
Key points covered:
Example: To find 54% of 750, first calculate 1% , then multiply by 54 to get 405.
Highlight: The page emphasizes the importance of understanding the relationship between percentages and decimals for efficient calculations.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀

This app is phenomenal down to the correct info and the various topics you can study! I greatly recommend it for people who struggle with procrastination and those who need homework help. It has been perfectly accurate for world 1 history as far as I’ve seen! Geometry too!
