This document discusses essential concepts of algebra including:
- Different types of numbers such as integers, rational numbers, irrational numbers, and complex numbers.
- Properties and rules for operations involving integers, fractions, order of operations, and factoring.
- How to perform operations like addition, subtraction, multiplication, and division on fractions and mixed numbers.
- Key terms like numerator, denominator, common factor, and lowest common multiple that are important for working with fractions.
Addition and subtraction integers
Standards: Recognize opposite signs of numbers as indicating locations on opposite sides of 0 on the number line; recognize that the opposite of the opposite of a number is the number itself, e.g., -(-3) = 3, and that 0 is its own opposite
Objective: Understand the rules to solve two term integer subtract problems.
Integers subtract
The document discusses subtracting integers. It explains that when subtracting integers with the same sign, the answer is always negative. When subtracting integers with different signs, subtract the smaller number from the larger number and the sign of the answer is the sign of the larger number. It provides examples of subtracting integers with both the same and different signs.
Integers
This document defines integers and the rules for adding and subtracting them. It explains that integers include all whole numbers and their opposites on the number line, including zero. It provides two main rules for adding integers: 1) if the signs are the same, add the numbers and use that sign, and 2) if the signs are different, subtract the smaller number from the larger and use the sign of the number with the larger absolute value. It also notes that subtracting a negative number is the same as adding a positive number.
Operations with integers
Integers include all whole numbers and their opposites, and zero. The key rules for operations with integers are:
1) Adding integers of the same sign yields a positive sum, while those of opposite signs subtracts and uses the sign of the larger number.
2) Multiplying and dividing integers follows sign rules - same signs yield a positive result, different signs a negative one.
3) To subtract integers, change the operation to addition by changing the subtraction sign to addition and changing the sign of the number being subtracted.
Understanding Integers
The document discusses different types of numbers:
1) Natural numbers are whole numbers starting from 1. Rational numbers can be expressed as fractions or decimals.
2) Integers include whole numbers and their opposites, as well as zero. They can be ordered and compared on a number line.
3) Rules for operating on integers include adding like signs and subtracting unlike signs, as well as products and quotients of the same or different signs being positive or negative.
Adding and subtracting integers
This document provides steps for adding and subtracting integers:
1) Determine if addition or subtraction is being asked and follow appropriate step. For subtraction, use the KCO method - Keep the first integer the same, Change the subtraction sign to addition, Change the second integer's sign to its opposite.
2) Add the integers if they have the same sign, subtract if they have different signs.
3) The answer will take the sign of the larger whole number.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes.

Unit 5 integers
- 1. I.E.S. MARÍA BELLIDO - BAILÉN 1º E.S.O. BILINGUAL SECTION – MARÍA ESTHER DE LA ROSA UNIT 1. INTEGERS 1. INTEGERS • Integers are like whole numbers, but they also include negative numbers ... but still no fractions allowed! The number line goes on forever in both directions. This is indicated by the arrows. • Whole numbers greater than zero are called positive integers. These numbers are to the right of zero on the number line. • Whole numbers less than zero are called negative integers. These numbers are to the left of zero on the number line. • So, integers can be negative {-1, -2,-3, -4, -5, … }, positive {1, 2, 3, 4, 5, … }, or zero {0} The integer zero is neutral. It is neither positive nor negative. • Two integers are opposites if they are each the same distance away from zero, but on opposite sides of the number line. One will have a positive sign, the other a negative sign. In the number line above, + 3 and - 3 are labeled as opposites. • We can put that all together like this: Z = { ..., -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, ... }
- 2. 2. COMPARING INTEGERS We can compare two different integers by looking at their positions on the number line. For any two different places on the number line, the integer on the right is greater than the integer on the left. Note that every positive integer is greater than any negative integer. Examples: 9 > 4 6 > -9 -2 > -8 0 > -5 3. OPERATIONS WITH INTEGERS 1. Adding Integers • When adding integers of the same sign, we add their absolute values, and give the result the same sign. Examples: 2 + 5 = 7 (-7) + (-2) = -(7 + 2) = -9 • When adding integers of the opposite signs, we take their absolute values, subtract the smaller from the larger, and give the result the sign of the integer with the larger absolute value. Example: 8 + (-3) = + 5 8 + (-17) = -9 2. Subtracting Integers • Subtracting an integer is the same as adding its opposite. Examples: 7 - 4 = 7 + (-4) = 3 12 - (-5) = 12 + (5) = 17 -8 - 7 = -8 + (-7) = -15
- 3. 3. Multiplying Integers Rules for Multiplication Positive x Positive Positive Positive x Negative Negative Negative x Positive Negative Negative x Negative Positive • Like signs yield a positive result. • Unlike signs yield a negative result. • If one or both of the integers is 0, the product is 0. Examples: 4 × 3 = 12 (-4) × (-5) = 20 (-7) × 6 = - 42 12 × (-2) = -24. 4. Dividing Integers The rules for division are exactly the same as those for multiplication. If we were to take the rules for multiplication and change the multiplication signs to division signs, we would have an accurate set of rules for division. Examples: 4 ÷ 2 = 2 (-24) ÷ (-3) = 8 (-100) ÷ 25 = -4
