Description

Whole numbers are counting numbers They start at 0 and go up to infinity Place values 57423 Place values start from the right most value and go toward the left most value Ten thousands:5 Thousandth:7 Hundreds:4 Tens:2 Ones:3 Subtraction The symbol used is the minus sign (-) B-a=c 9-3=6 -3+9=6 3-9=-6 -1-4=5 8-20=-12 13-10=3 -4-9=-13 -9+8=-1 746 - 28 718 Multiplication: is used to simply repeated addition the result of multiplying 2 or more numbers is a product. The numbers being multiplied are called factors Division:The process of separating a quantity into groups of equal size Powers/exponents: used to simply repeated multiplication Properties of exponents:multiplying same bases means add the 2 powers 2^3•2^4=2^7 Quotient rule: Chapter 3 fractions: A fraction is a number of the firm a/b,a and b are internet’s b=0 with is undefined A fraction is called a rational number the top number is the numerator and the bottom is the

denominator the division line that separates the numbers is called the fraction bar Factors: any whole numbers that can be multiplied together to equal ex.24 are factors of 24 Divisibility: If a and b are natural number, a is divisible by b if the operation of dividing a by b,leaves a remainder of 0, this is the same as saying b is a divisor of a, or b divides a Prime numbers: A natural number greater than 1 that is only divisible by 1 and itself Composite number: A natural number greater than 1 that is divisible by a number other than itself Prime factorization: Expressing a composite number as the product of prime numbers Greatest common factor (GCF): Largest factor of both numbers Reciprocals: 2 Numbers are reciprocals or multiplicative inverse if their product is 1 Dividing fractions: The quotient of two fractions is the first fraction multiplied by the reciprocal the second fraction Unit Rates: 1. Write the rate in fraction interpret with the units included 2. Divide the numerator and the denominator. The result is a unit rate with a denominator of 1...
