Math Vocab: 8th Grade

What is an inequality?

• treating two numbers the same

• the relation between two expressions that are not equal

• an inverse operation

Tags

CCSS.6.EE.B.8

Inequality symbols:

• show if one value is equal to another

• show if one value is less than, greater than, or not equal to another value

• are not valid unless two values are equal

What is the definition of one solution?

• no matter what constant is substituted in for the variable, the equation is ALWAYS true

• only this ONE solution will make the equation true

• no matter what constant is substituted in for the variable, the equation will NEVER be true

Combine like terms:

• similar solutions to different problems

• a process used to simplify an expression - terms that have the same variable part are combined using addition or subtraction

• multiplying the simplest form of an equation to find the distributive property of a solution

What is distributive property?

• to subtract two like terms from the coefficient solution in order to solve for x

• the degree to which an equation is solved for like terms

• to divide something or give a share or part of something

What is an inverse operation?

• an equation that solves for the exponent to the third power

• the operation that reverses the effect of another operation

• one part of an expression that simplifies the square root of a solution

What is a coefficient?

• a number used to multiply a variable

• the order of operation for submitting a solution

• the variable of a letter

What is a variable?

• a symbol for a value we don't know yet - is usually a letter like x or y

• subtracting the answer from the solution

• an expression written in simplified form
