The student is expected to add, subtract, multiply, and divide decimals and whole numbers to solve meaningful problems. When adding decimals, the decimals must be lined up. When subtracting decimals, the small number is subtracted from the large number and the decimals must be lined up. For multiplication, the last digit of the second number is used first. For division, the large number goes inside the "house" and any remainder is written on the side.

Word problems can be solved using the ESA method which stands for writing the Equation, finding the Solution, and stating the Answer. Key words that indicate addition is needed include add, altogether, both, more than, in all, plus, sum, total, combined, and join.
Addition of Numbers
Addition is putting together two or more sets to form a new set. It uses the symbol plus (+) to represent combining numbers. The addends are the numbers that are added together, and the sum is the result of adding two or more numbers. For example, in the addition sentence 2 + 1 = 3, the addends are 2 and 1, and the sum is 3. Practice problems are provided to help understand addition.
Multiplication
This document introduces multiplication as both repeated addition and an array. It uses counters arranged in rows and columns to demonstrate that the number of rows multiplied by the number of columns equals the total number of counters. Several examples show writing multiplication sentences to represent the rows and columns as well as equivalent addition sentences by adding the number of counters in each column. The document concludes by using word problems to further illustrate multiplication as repeated addition to calculate how many items are bought for a given number of friends.

Tips And Tricks To Do The Match Quickly
Most of the people don’t like to do the math, and when it comes to the use of large fractions, they are always the source of irritation to such people at the first moment. If you want to learn the techniques to do the match quickly and easily, then have a look at all the tips listed below to get the most benefit.
7th integers class 7 ppt
Integers include all whole numbers from negative infinity to positive infinity, including zero, and are denoted by the letter Z. On a number line, positive integers are to the right of zero and negative integers are to the left. The additive inverse of a number is its opposite - for example, the additive inverse of 5 is -5. To subtract integers, the subtraction sign is changed to addition and the number after the sign is changed to its opposite. This allows subtraction problems to be solved as addition problems.

This document provides instruction on adding integers. It begins with objectives and essential questions about how adding integers differs from adding whole numbers and how the sign of integers affects their sum. It then presents two rules for adding integers: 1) if integers have the same sign, add the numbers and keep that sign, and 2) if integers have different signs, subtract the numbers disregarding sign and keep the sign of the integer farther from zero. Examples demonstrate applying each rule. The document concludes by providing practice problems for students to solve.

“I’m still / I’m still / Chaining from the Block”
“An Outlook of the Ongoing and Future Relationship between Blockchain Technologies and Process-aware Information Systems.” Invited talk at the joint workshop on Blockchain for Information Systems (BC4IS) and Blockchain for Trusted Data Sharing (B4TDS), co-located with with the 36th International Conference on Advanced Information Systems Engineering (CAiSE), 3 June 2024, Limassol, Cyprus.
Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Artificial Intelligence for XMLDevelopment
In the rapidly evolving landscape of technologies, XML continues to play a vital role in structuring, storing, and transporting data across diverse systems. The recent advancements in artificial intelligence (AI) present new methodologies for enhancing XML development workflows, introducing efficiency, automation, and intelligent capabilities. This presentation will outline the scope and perspective of utilizing AI in XML development. The potential benefits and the possible pitfalls will be highlighted, providing a balanced view of the subject.
We will explore the capabilities of AI in understanding XML markup languages and autonomously creating structured XML content. Additionally, we will examine the capacity of AI to enrich plain text with appropriate XML markup. Practical examples and methodological guidelines will be provided to elucidate how AI can be effectively prompted to interpret and generate accurate XML markup.
Further emphasis will be placed on the role of AI in developing XSLT, or schemas such as XSD and Schematron. We will address the techniques and strategies adopted to create prompts for generating code, explaining code, or refactoring the code, and the results achieved.
The discussion will extend to how AI can be used to transform XML content. In particular, the focus will be on the use of AI XPath extension functions in XSLT, Schematron, Schematron Quick Fixes, or for XML content refactoring.
The presentation aims to deliver a comprehensive overview of AI usage in XML development, providing attendees with the necessary knowledge to make informed decisions. Whether you’re at the early stages of adopting AI or considering integrating it in advanced XML development, this presentation will cover all levels of expertise.
By highlighting the potential advantages and challenges of integrating AI with XML development tools and languages, the presentation seeks to inspire thoughtful conversation around the future of XML development. We’ll not only delve into the technical aspects of AI-powered XML development but also discuss practical implications and possible future directions.

CAKE: Sharing Slices of Confidential Data on Blockchain
Presented at the CAiSE 2024 Forum, Intelligent Information Systems, June 6th, Limassol, Cyprus.
Synopsis: Cooperative information systems typically involve various entities in a collaborative process within a distributed environment. Blockchain technology offers a mechanism for automating such processes, even when only partial trust exists among participants. The data stored on the blockchain is replicated across all nodes in the network, ensuring accessibility to all participants. While this aspect facilitates traceability, integrity, and persistence, it poses challenges for adopting public blockchains in enterprise settings due to confidentiality issues. In this paper, we present a software tool named Control Access via Key Encryption (CAKE), designed to ensure data confidentiality in scenarios involving public blockchains. After outlining its core components and functionalities, we showcase the application of CAKE in the context of a real-world cyber-security project within the logistics domain.
