Multiplying Decimals

This section presents a detailed methodology for decimal multiplication through a clear three-step process. The page demonstrates multiple examples with varying decimal places to reinforce the concept.

Definition: When multiplying decimals, the process involves treating the numbers as whole numbers initially, then adjusting the decimal placement in the final answer.

Example: Multiplying 4.3 × 5.2:

  1. Multiply 43 × 52 = 2236
  2. Count decimal places 1in4.3+1in5.2=2total1 in 4.3 + 1 in 5.2 = 2 total
  3. Place decimal point 2 places from right: 22.36

Highlight: The total number of decimal places in the product equals the sum of decimal places in the factors.

Dividing Decimals

The final page explains the process of decimal division through a clear, step-by-step approach focusing on decimal point manipulation and standard long division.

Definition: Decimal division involves strategically moving decimal points in both the dividend and divisor before performing standard long division.

Example: Dividing 5.525 ÷ 4.25:

  1. Move both decimals right until divisor becomes whole number
  2. Perform long division
  3. Place decimal in quotient based on dividend's decimal position Result: 1.3

Highlight: The key to successful decimal division is ensuring the divisor becomes a whole number through decimal point movement, while maintaining the relative value of both numbers.

Divisibility Rules

This page outlines comprehensive rules for determining divisibility of numbers from 2 through 10. Each rule provides a unique method for quick mental calculations without performing long division.

Definition: Divisibility rules are mathematical shortcuts that help determine if one number is divisible by another without performing actual division.

Example: To check if a number is divisible by 3, add all its digits. If the sum is divisible by 3, the original number is divisible by 3. For instance, 126: 1+2+6=9, and 9 is divisible by 3, so 126 is divisible by 3.

Highlight: The rules for 2, 5, and 10 are the easiest to apply as they only require looking at the last digit of the number.

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.

Samantha Klich

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

Brad T

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!
