Prepare to be amazed!
I CAN read your mind - but is this math or is it magic?

This trick fools magicians - because it doesn't use sleight of hand - it uses the Kruskal count.

In this lesson, you will learn to multiply fractions quickly and easily.
To multiply fractions you multiply across the numerators (the top number of a fraction) and multiply across the denominators (the bottom number).

An example I always use to start this off is multiply 1/2 with a 1/2. The numerators multiply to give 1 (1 x1), the denominators multiply to give 4 (2x2). Hence a 1/2 multiplied by a 1/2 is 1/4.

What about if you multiply 2/3x1/4?
Top number (2x1), bottom number (3x4).
So 2/3x1/4 = 2/12. To donate to the tecmath channel: https://paypal.me/tecmath?locale.x=en_AU To donate to the tecmath channel: https://paypal.me/tecmath?locale.x=en_AU

Trigonometry is an easy way to work out the unknown sides and angles of a right angled triangle. The trick - know the side names - the opposite, hypotenuse, and adjacent, and know how and when to apply the trigonomic functions - sin, cos and tan. this is the only trick to getting it right every time!
In this lesson, students learn work out unknown angles using use sine, cosine, and tangent. You will need a scientific calculator for the problems in this lesson - and I'll show you how to access one on your computer.

To work out the fraction of an amount, first of all it is essential to convert the fraction to a decimal.
To do this divide the numerator (top number) by the denominator (bottom number). eg - 1/5 = 0.2 Then times this answer by the amount you wish to find a fraction of.
e.g 1/5 of 20 = 0.2 x 20 = 4
To work out the percentage of an amount, it is also essential to first convert the percentage to a decimal.
To do this move the decimal place left two spaces - eg - 25% = 0.25 Then times this answer by the amount you wish to find apercentage of.
e.g 25% of 20 = 0.25 x 20 = 5. To donate to the tecmath channel: https://paypal.me/tecmath?locale.x=en_AU To donate to the tecmath channel: https://paypal.me/tecmath?locale.x=en_AU

How do you solve conditional probability examples?
What is the probability of an event A given that event B has occurred?
This is conditional probability, solved by the formula that P(A|B) which reads "probability of A given B" is equal to the P(A intersect B)/P(B).
Three examples are examined.

Use this math trick to fool your teacher, trick your friends or possibly get in an argument. Better yet learn how to avoid making these mistakes in your own reasoning.

Join us on this geometry translations practice problem where you have to describe a transformation.

Join us on this flipped math lesson for CCLS 8.G.A.2 where we work through a problem that was inspired by a released common core exam item where we explore how to describe a sequence of transformations between two congruent triangles on the coordinate plane.

This lesson answers the question: What is a translation? How do I translate a figure? What is the difference between a rotation and a reflection? What is a dilation? What is a sequence of transformations? How do I describe a transformation?

Our lessons are perfect for flipped classroom math teachers and students and for warm-up and exit ticket activities . This lesson is aligned with the 8th grade common core math learning standards for math and the SAT math curriculum as well.
