Examples are given to show how expressions represent relationships between quantities. Words that indicate addition, subtraction, multiplication and division are listed. Practice problems are included to write expressions for word phrases and situations. The key aspects covered are variables, expressions, evaluating expressions, and writing expressions from word problems.
Math 7 lesson 8 multiplication of integers
The document discusses multiplication of integers. It explains that multiplying integers involves multiplying signed numbers, and that the product of the absolute values remains the same but the signs may differ. It provides two rules for the sign of the product: if two integers have the same sign, the product is positive, and if they have opposite signs, the product is negative. Examples are given to illustrate the rules.
Signed numbers
The document discusses absolute value and operations involving positive and negative numbers. Absolute value only expresses distance from zero and is always positive. Addition and subtraction of numbers follow specific rules depending on their signs: for addition the signs are kept or changed, for subtraction the operation is changed to addition and the second number's sign is changed. The same rules for sign of the product apply to both multiplication and division.

Definitions
The document defines integers and their properties. Integers include positive numbers like 1, 2, 3, and their opposites -1, -2, -3, called negative numbers, as well as zero. The integers follow rules like -(-3) = 3, and for any integer n, n + -n = 0. Integers can be visualized on a number line with equally spaced points labeled with numbers, showing their relative positions and how they increase or decrease in the positive direction.

The document discusses integers and their properties. It defines integers as the set of numbers {..., -3, -2, -1, 0, 1, 2, 3, ...} which includes natural numbers, whole numbers, and their negatives. A number line is used to represent integers visually with negatives to the left of 0 and positives to the right. Rules for addition and subtraction of integers are provided, such as keeping the sign of the number with the greater magnitude. Multiplication and division of integers results in a positive answer if there is an even number of negative factors and negative if there is an odd number.

1) When multiplying integers with the same sign, the product is positive, but with different signs, the product is negative.
2) For exponents, if the base is in parentheses, you raise that number to the power. If the base is negative without parentheses, you raise the absolute value to the power and then make the answer negative.
3) The distributive property distributes the number being multiplied over terms in parentheses by multiplying each term individually and then combining like terms.
Integers
The document discusses integers and the number line. It introduces addition and multiplication rules for integers.
- Integers include whole numbers and their opposites, and are represented on the number line.
- For addition, the sign of the sum is the same as the signs of the addends if they are the same, and follows the sign of the larger addend if the signs are different.
- For multiplication, the product is positive if the factors have the same sign and negative if the signs are different.
Integers
Integers include whole numbers and their negatives, and can be located on the number line. Positive integers are to the right of zero, negatives are to the left, and zero is neutral. Integers can be compared by their positions, with larger numbers further right. Operations with integers follow rules where like signs yield a positive result, unlike signs a negative result, and zero as a product or dividend yields zero.

The Mayan language was spoken by millions in Mesoamerica from 500 BCE to 1200 CE. It is still spoken by 6 million people today and has 21 different versions. The earliest Mayan writings date to 250 BCE and their complex writing system included 550 logograms representing words, 150 syllabograms representing syllables, and 300 glyphs, with 100 glyphs used specifically for names of gods. The language commonly uses prefixes and suffixes added to words.

It explains that the + sign means to move to the positive side of the number line and the - sign means to move to the negative side. It provides examples of adding (+2) + (+4) = +6 and subtracting (-3) - (-1) = -5 on the number line. It also notes that when multiplying a number by a signed number, you add or subtract that number to itself the same number of times to the positive or negative side depending on the sign. Finally, it explains that you can use a number line to divide by splitting it into equal parts.

This forced Joshua, Sion, and Moab - three friends living in Israel - into servitude, making mud bricks for 16 hours each day with only 7 hours to sleep. After three years of these conditions and many deaths, the three friends led an uprising where they stole swords at 4 am and killed the Babylonians, liberating Israel from slavery and allowing the people to live happily again.
