2 + 2 = 4. That's about as much math as I can handle without a calculator on a daily basis. I literally hate doing math more than anything in life, mostly because I'm not good at it—and I hate doing things I'm not good at.
This video is a tutorial on how to perform the multiplying chalk trick. The magician uses two pieces of chalk to perform this trick, although he also suggests using anything chalk-shaped. First, the magician performs the illusion of hiding one piece of chalk in his right hand. The other chalk is visible to the audience in his left hand. He switches the chalk and pretends to put it in his pocket, but in reality he is hiding the piece of chalk. He continues to repeat this action over and over. ...
In this tutorial, we learn how to solve inequalities by multiplying or dividing. Start out with your equation written out in front of you. Now, find the variable in the equation and figure out how to get rid of the denominator underneath it. Divide this on both sides, then you will be left with the variable with the inequality. Don't flip the inequality if you don't divide by a negative on both sides. Then, write out the rest of the equation. Once finished, do the rest of the math for the rig...

Most of the time, when I’m bored during math class, I play with my calculator to satisfy my boredom. Recently, I've discovered that when multiplying any number by 11, 111, or any number similar to it, that it has a pattern (though I guess everything in math has a pattern). I don't know if this technique is original, because I didn't read anything about this. It's just mere observation. If it’s a tried and true technique, let me know.
Multiplying fractions are very simple, just multiply the numerators of the fractions to get the new numerator, and multiply the denominators of the fractions to get the new denominator. Let's say we have 2 fractions 1/2 and 1/2 when multiplying them 1/2x1/2=1/4 [1x1/2x2].
Doug Simms gives a demonstration of multiplying fraction in a simple and easy manner. The simplest problems have proper fractions to be multiplied by proper fractions, and the answer can be arrived at by simply multiplying the numerator (upper value) of one fraction with the numerator of the other, carrying out the same operation with the denominators (lower values) of the two fractions, and finally, reducing the resultant fraction by a common factor, if any. Doug also gives three other examp...
This video shows the basics of multiplying integers. The main point that people can struggle with is the variation of signs. When multiplying integers you must always be aware of the positive and negative numbers. When you multiply two numbers that have the same signs, both positive or both negative numbers, this will always generate a positive answer. If there is one positive and one negative number this will always lead to a negative answer. This video shows very basic problems of multiplyi...

When dividing, you simply flip the second fraction over and multiply straight across like normal. When multiplying a whole number and mixed number, simply put the whole number over one. Then, convert the mixed number into an improper fraction. Then, multiply the mixed number with the numerator and add in the d...
This video shows us how to multiply mixed numbers with the whole numbers. First thing you need to do is to change the mixed number into an improper fraction by multiplying the denominator with the whole number and add the resulting number with the numerator. The resulting number will be placed as a numerator with the denominator being the same. Next, is that we can't multiply a fraction with a whole number. So we need to change the whole number into a fraction and this is done by putting the ...
Multiplying polynomials is a distributive property. If you are given with two binomials and asked to multiply them, you need to apply the distributive property and multiply the terms of binomial with the terms of second binomial. To do this first take a term of first binomial and multiply it with the second complete binomial. Now take the second term of first binomial and multiply it with the second binomial adding or subtracting it from the previous result depending on the sign between the f...
