MATH 19500 Chapter Notes - Chapter 1: Coen Tunnel, Distributive Property, Real Number
Document Summary
Every number has 1 and itself are factors. Integers: german work for integers starts with z. ( negative, positive numbers including zero) Rational numbers: [ a/b] where a and b are integers. (positive and negative fractions). ----------------------------------------------------> there"s a coentunnel if numbers,numbers that always represents something. Ratiotional number: decimals that can be written as fractions. Associative properties: a+b+c = (a+b)+c, a+(b+c) grouping does not matter, you"ll still derive to the same number. Same goes for multiplication ab(c)= a(bc) order does not matter. Distributive property: how do addition and multiplication interact? a(b+c) = a(b)+ a(b) (a+b)c= a(c)= b(c) Distributing property helps to break down problems, and help with mental math. A product of identical numbers is usually written in exponential notation. Solve for the width in terms of lengths and area. You have to subtract the length (l) on both sides and you"ll get w= a/l. Solve for r in terms of t and d,
