numbers smaller than 0

a(b+c) = ab + ac and a(b-c) = ab - ac 2(5+3)=(2x5)+(2x3) and 2(5-3)=(2x5)-(2x3)

How you get the answer to an equation

When 0 is added to any number, the sum is the number. Example: 5 + 0 = 5

decimals that never end and repeat the same digits over and over

numbers that can be written as fractions (a/b) and b cannot = 0

numbers larger than 0

a+(b+c)=(a+b)+c and (ab)c=a(bc) Ex:(2+3)+4= 2+(3+4) and (2x3)x5=2x(3x5)

When any number is multiplied by 0, the product is 0. Example: 3 x 0 = 0

a mathematical phrase that can contain numbers, operations, and variables

the work to show the answer of an equation

two numbers whose sum equals 0

When any number is multiplied by 1, the product is the number. Example: 1 x 8 = 8

decimals that end and whose only repeating number is zero

numbers that can be whole numbers, zero, and their opposites

the distance from zero

to find the value of numerical or algebraic expressions

the order in which two numbers are added or multiplied does not change their sum or product
