SAT Math is big on real-life word problems, this tests not only your knowledge of the theory about the linear equations, but also your ability to apply that theory. Here is a process for approaching SAT Math word problem: Quickly scan the problem. Decide for yourself if you’re familiar with it enough to spend time…
You will encounter at least one factoring problem on SAT Math test. This post walks you through how to factor a quadratic equation from an expanded form into the factored form. The expression in the expanded form looks like this X2 + bX + c = 0 But the same expression with factors looks like…
What Is An Algebraic Expression? First off, the word “algebraic” comes from the word “algebra.” Algebra comes from Arabic word “al-jabr,” which means the reunion of broken parts. And “al-jabr” comes from Arabic “jabara”, which means reunite, restore. So “algebra” means the science of restoring what is missing and equating like with like. When you…
Factoring is an essential tool in algebra and for SAT math problem solving. It comes from the word “factor,” which means “An integer that divides into another integer exactly.” Like 2 divides into 8, also 4 divides into 8. So 2 and 4 are factors of 8, because 8 is divisible by them. 8 :…
