Page 2: Mean Value Calculation

This page explores finding a missing number in a set when given the mean value and other numbers in the set. The problem demonstrates understanding of averages and numerical relationships.

Vocabulary: Mean is the average of a set of numbers, calculated by dividing the sum by the count of numbers.

Example: With four known numbers 13,12,9,1613, 12, 9, 16 and a mean of 12, the fifth number can be found by: 12×512 × 5 - 13+12+9+1613 + 12 + 9 + 16 = 10

Highlight: The solution involves working backwards from the desired mean to find the missing value.

Page 3: Weight and Distance Calculations

This page covers two distinct problems: calculating the empty weight of a chocolate box and determining distance traveled by a tortoise.

Example: For the chocolate box:

  • Initial weight: 290g with 7 chocolates
  • After eating 3 chocolates: 194g
  • Empty box weight: 32g

Highlight: The tortoise problem involves converting time and distance measurements, showing that in 2 hours 8×15−minuteintervals8 × 15-minute intervals, the tortoise walks 13.6km.

Definition: Rate of travel is the distance covered in a given time period, used to calculate total distance over longer durations.

Page 1: Square and Triangle Area Calculation

This page focuses on calculating the area of a square using information about an equilateral triangle. The problem demonstrates the relationship between perimeter and area in geometric shapes.

Definition: Perimeter is the total distance around a shape, while area is the space inside the shape.

Example: When the perimeter of an equilateral triangle is 36cm 12cm+12cm+12cm12cm + 12cm + 12cm, and it equals the square's perimeter, each side of the square must be 9cm 36cm÷436cm ÷ 4.

Highlight: The area of the square is calculated by multiplying the length by width: 9cm × 9cm = 81cm².

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.

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

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!

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
