Accentuate the Negative

integers Whole numbers and their opposites.
negative numbers a number less than 0.
opposites two numbers whose sum is 0.
positive numbers a number greater than 0.
rational numbers a number that can be represented as the quotient of two integers with the divisor not being 0.
algorithm Steps you follow to solve a problem.
Commutative Property Order doesn't matter in addition or multiplication.
absolute value the distance a number is away from 0 on a number line.
additive identity For rational numbers, it's zero. Add zero to any rational number and the sum is the original number. ex:1/2 + 0 = 1/2
additive inverse Two rational numbers that when added together equal zero. ex: (+3/4) + (-3/4) = 0
multiplicative identity For rational numbers it's 1. This means that you can multiply any rational number by 1 and you will end up with your original number. ex: -3/5 x 1= -3/5
multiplicative inverses Two numbers that can be multiplied together to equal 1. ex: 4 x 1/4 = 1
Order of Operations the order that all operations must be done in. "Please excuse my dear aunt Sally" or P.E.M.D.A.S: parenthases & exponents, multiplication & division, then addition & subtraction
Distributive Property 2 (3+4) = (2x3) +(2x4)
expanded form The form of an expression made up of sums or differences of terms rather than products or factors. ex: 15+5
factored form The form of an expression made up of products rather than sums for differences. ex: 5( 3+1)
number sentence A mathematical statement that gives the relationship between two expressions, made up of numbers and operation signs.
