Substitution 13•n 13•3 13•3=39 N=3 Exponents 5(3)= 5•5•5 Pemdas Parenthesis Exponents Multiplication Division Addition Subtraction Absolute Value The distance from zero on a number line it is always positive |-3|=3 |3|=3 Multiplication and Division with Fractions Positive times positive is positive 4•3=12 Negative times negative is positive -5•-5=25 Negative times Positive is Negative -4•4=-16 Addition and subtraction Positive plus positive is positive 8+8=16 Negative plus Negative is Negative -5+-4=-9 Negative plus positive is well it depends you'll want to subtract the absolute value of the two numbers larger minus smaller and make the sign the same sign of the largest absolute value of the numbes Operation Vocal The answer to a Addition= sum Multiplication = product Subtraction= difference Division= quotient Ex. The sum is 30 and b is 100 Commutative property Changing the order of the numbers will not change the result Associative Property Changing the grouping of the numbers will not change the result Identity Property Zero and one preserves identities under addition and multiplication respectively Distributive Property Multiplication distributes over the addition A(b+c)=ab+ac Practice identifying the Property Ex: 19•5=5•19 Solving equations Equations are statements formed by placing an equal sign between two mathematical expression. Ex: x+2=5 Defined words and important things to know about
