Operations with IntegersIntegrated Mathematics
Addition Rules Positive + Positive = PositiveNegative + Negative = Negative Positive + Negative or Negative + Positive Subtract & Take Sign of Number Further from Zero
Addition Rules When the signs are the SAMEAdd and keep the Same Sign When the signs are DIFFERENT Subtract and keep the sign of the number further from ZERO
Adding Integers Ex.1) −𝟑+𝟓 Ex.2) −𝟒+(−𝟓) Ex.3) −𝟒+𝟗 Ex.4) −𝟓+𝟐
Adding Integers Ex.5) −𝟏𝟐+(−𝟕) Ex.6) 𝟏𝟑+(−𝟕) Ex.7) −𝟏𝟓+𝟏𝟎 Ex.8) −𝟏𝟐+𝟐𝟓
Practice -4 + 10 6) 9 + (-16) 5 + (-2) - 8 + (-8) -3 + (-7) 13 + 05 + (-5) 6) 9 + (-16) - 8 + (-8) 13 + 0 11 + (-6)
Subtraction Rules Ex.11) −𝟑−𝟒 Ex.12) −𝟖−(−𝟓) Ex.13) −𝟒−(−𝟔) Ex.14) 𝟐−𝟔Use Addition Rules Make two minus signs into a plus sign Ex.11) −𝟑−𝟒 Ex.12) −𝟖−(−𝟓) Ex.13) −𝟒−(−𝟔) Ex.14) 𝟐−𝟔
Subtracting Integers Ex.15) 𝟒−𝟗 Ex.16) 𝟔−(−𝟒) Ex.17) −𝟒−𝟏𝟕
Rules for Multiplication/DivisionWhen the signs are Different, the answer is Negative. When the signs are THE SAME the answer is Positive. RULES + -
Multiplying Integers Ex.19) 8(− 5) Ex.20) (−𝟕)∙𝟓 Ex.21) (−𝟑)(−𝟒)
Dividing Integers Ex.25) 15÷ −3 Ex.26) −21÷(−7) Ex.27) −44 −11
2.1 Integers & Absolute Value 2.2 Adding Integers.
Laws of Exponents. Remember: Rule 1—Multiplying like bases When multiplying like bases, keep the base and ADD the exponents.
NO CALCULATORS!!!!!!!. Integers are the whole numbers and their opposites (no decimal values!) Example: -3 is an integer Example: 4 is an integer.
How to work out Integers using BEDMAS
INTEGERS: adding, subtracting, multiplying, and dividing
Objective: Learn to multiply and divide integers.
ADDING INTEGERS (SAME SIGNS)
Grade 9 Integer Review Review Day 1.
Multiplying and Dividing Integers 1.9. Rules: Multiply or divide SAME sign the product or quotient is POSITIVE Examples: 1.) -2∙ (-22)= 2.) -45÷ (-9)=
Integers. Adding integers Both positive…add as usual Both negative…add as usual and answer is negative Positive and negative…subtract…take the sign of.
Integer Rules. Adding with the same sign Rules Rules Add like normal Add like normal Keep the sign Keep the sign Examples Examples = -22 (all.
ALGEBRA 1 Operations with Integers
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.
Unit 1: Number Sense Minds On. Unit 1: Number Sense Review: Operations with Negative Numbers Learning Goals: I can add and subtract negative numbers I.
