The Basics
This term refers to a letter or symbol used to represent an unknown number.
What is a variable?
x-12=15
What is x = 27?
This is the standard geometric formula used to find a missing side of a right triangle.
What is a2 + b2= c2 ?
This is the name given to the number that multiplies a variable, such as the 5 in 5x.
What is a coefficient?
Solve for 4y = -32
What is y = -8?
Find the hypotenuse (\(c\)) of a right triangle if the two legs are \(a = 3\) and \(b = 4\).
What is 5?
In an algebraic expression, these are the parts separated by plus or minus signs.
What are terms?
Solve for m: 3m + 5 = 20.
What is m = 5?
This mathematical property states that (a(b + c) = ab + ac)
What is the distributive property?
Solve for g: (g/3) - 4 = 2
What is g = 18?
This is the key difference between an expression and an equation
What is an equals sign (=)? (Equations have them; expressions do not.)
Solve for k: 7 - 2k = 15
What is k = -4?
