SAT Prep is an important topic, but you do not need to approach it with fear. Each Saturday, two questions will be posted similar to the type you will find on the mathematics section of an SAT test.* The following week, I will provide the answer along with two new questions. These questions are good practice for the PSAT or the ACT as well.

* I am creating these myself, based on available SAT test materials (so that I do not infringe on copyright laws).

SAT Question 1.        (Algebra 1)

The function f(x) is defined as f(x) = 3g(x), where g(x) = x + 2. What is the value of f(5)?

SAT Question 2.       (Math)

Maria has an average of 81 in her English class after taking 6 quizzes. If her lowest score is removed, her average rises to 85. What was her lowest score?

1. 66 points
2. 61 points
3. 75 points
4. 81 points

Remember, the answers will be posted next Saturday along with an explanation of how we get to those answers.

Please, contact me at info@mytutorlesson.com if you have an SAT question you would like to ask. Some will be answered directly and some will be posted here to be shared.

ASK A MATH TEACHER

Today’s question comes from the internet.

How Do You Remember the First Few Digits of Pi?

Me personally, I was taught the first ten digits of pi by remembering a sentence: “How I Wish I Could Eliminate My Energy Bills Now.” How has three letters; I is one letter; Wish is four letters, and so on. π = 3.141592653

There are other sentences you can use.

Wow! I made a great discovery! (3.14159)

How I wish I could calculate pi. (3.141592)

May I have a large container of coffee beans? (3.14159265)

See, I have a rhyme assisting my feeble brain; its tasks sometime resisting. (3.141592653589)

And one in French: Moi, j’aime a faire connaitre un nombre utile aux sages. (3.1415926535)

Roughly translated, this means “I like to teach a number useful to wise men.”

Try singing this one for 7 digits. Use the tune of “Twinkle, Twinkle, Little Star”

Cosine, secant, tangent, sine

Three point one four one five nine.

I hope one of these mnemonics works for you!
