Day 4 Name all the sets of numbers to which each number belongs to:

Adding and Subtracting Integers

Adding and Subtracting Integers. RULE #1: Same Signs!! When you’re adding two numbers with the same sign, just ignore the signs! Add them like normal!

2.1 Integers & Absolute Value 2.2 Adding Integers.

RATIONAL NUMBERS NATURAL NUMBERS {1, 2, 3,…}+ {0} = WHOLE NUMBERS {0, 1, 2, 3,…}+ NEG. WHOLE NOS. = INTEGERS {…-2, -1, 0, 1, 2,…}+ PURE FRACTIONS = RATIONAL.

Adding rational numbers Essential question: How can you add rational numbers? Unit 1-2.

Subtracting Rational Numbers

POSITIVE AND NEGATIVE NUMBERS

NO CALCULATORS!!!!!!!.  Integers are the whole numbers and their opposites (no decimal values!)  Example: -3 is an integer  Example: 4 is an integer.

Adding Integers. Adding Integers with the Same Sign Add the absolute values. The sum will have the same sign as the addends. Example 1 Find –2 + (-3)

INTEGERS: adding, subtracting, multiplying, and dividing

ADDING INTEGERS Positive + Positive = Positive Positive + Positive = Positive ( +3) + (+2) = +5 ( +3) + (+2) = +5 When a number is positive, you do not.

Rules of Integers. Positive numbers are numbers that are above zero. Negative numbers are numbers below zero.

Remember Lesson 6 when we added Integers – follow the same rules to add rational numbers. Positive + Positive = Positive Positive (Bigger number) + Negative.

ADDING & SUBTRACTING RATIONAL NUMBERS By Miriam Herrera, Anayeli Moreno, & Isabel Turijan Pd.7

ADDING & SUBTRATING RATIONAL NUMBERS Vocabulary ~ Integers – include postive and negative whole numbers as well ~ subtration – opposite of addition ~ Addition – uniting two or more numbers into a sum ~ Rational Numbers – a number that can be expressed exactly by a ratio of two numbers

ADDING AND SUBTRACTING RATIONAL NUMBERS Rational Number Rules Same signs = ADD Different signs = SUBTRACT (The bigger he number is called the bully ) Examples: = = -17

ADDING AND SUBTRACTING RATIONAL NUMBERS Try It = 8 Do they have the same sign ? Yes, I need to add the both negatives The bully is 5. My result is negative !!!!!!!
