Math homework isn't the easiest thing to get through quickly, no matter how prepared you are. Knowing your stuff simply won't cut it. Going through dozens of equations in one sitting could take up hours of your time. Even when you finish, there's always going to be that one problem you couldn't solve, which could take hours itself to finally get right.
It may seem elementary to some, but there are still those (especially young children) who cannot add two numbers together. The easiest way to start out with addition is with the number line trick. This math video shows you the quick trick to learning simple addition problems. From here, things only get tougher.
In this math lesson we will learn how to solve simple probability problems with a number cube. The probability of an event measures the likelihood that the event will occur.

In this video, we learn how to make an Escher-esque tessellation. Start with construction paper, then make an equilateral triangle onto it. Next, make a shape on one end of the triangle, making any shape you would like. Now cut your shape out, then trace it onto another piece of construction paper. After this, rotate the shape over on the second piece of paper, then trace it out again. The lines should match up equally. You will then have one side left, which you will use to make any shape yo...

This video is a simple math video showing how to add and subtract fractions using different denominators. It begins with a man explaining briefly and sitting in front of a piece of paper. He writes out a group of fractions each one with different denominators, ending in three and five. To add appropriately, on must find a common denominator, which is fifteen. So he multiplies each by five and three, raising the denominators to fifteen. This will raise the fractions to six-fifteenths and twent...
Learn how to convert from scientific notation to standard form by watching the above math video. To change a number from scientific notation to standard form, move the decimal point to the left (if the exponent of ten is a negative number), or to the right (if the exponent is positive). You should move the point as many times as the exponent indicates. Do not write the power of ten anymore.

Before the calculator and even the abacus was invented, there was a little instrument called the human brain that we used to do math. Remember that? While most of us turn to our trusty Ti-84s to do calculus homework or whip out our cell phone calculators to determine how much we should tip at Johnny Rocket's, it can often be much faster to use our own brains, along with a piece of paper and pencil.
Though impressive, reading minds in person has been done and overdone. Revamp this tired sport by learning how to mind read over the phone and even on Twitter.

We're all feeling the impact of the economic recession underway due to the coronavirus. With millions of Americans filing for unemployment benefits, now more than ever should we focus on the best deal rather than the best model. And in no industry is that more evident than smartphones.
Not all microwaves are created equal, so when you use the recommended cooking time on any microwaveable meal, chances are you're actually cooking the food too much or not enough. And unless you're really good at mental math or have a virtual assistant that's smarter than Siri and Google, you have to do things the long way — but not with these helpful apps for iOS and Android.

Like many others, I like a good cocktail every now and then, and I've always been impressed when my cocktail enthusiast friends would come up with a new drink or even just remember how to concoct a Clover Club (FYI, it's made with gin, raspberry syrup, lemon, and egg white). There's a secret bartenders and craft cocktail aficionados know, though: It's all about math, the simplest and most intoxicating math. Pythagoras would be so proud.

This video teaches us the method to simplify the fractions. Let us take an example of 18/24. Find a number that goes into both 18 and 24. Divide the top and bottom by the same number. Here, 2 will go into both numbers. So, the number now becomes (18/2)/(24/2) which gives 9/12. This fraction can be further simplified by dividing the top and bottom by 3. We get 3/4 which is our final answer. The fractions 18/24, 9/12 and 3/4 are called equivalent fractions since they are of the same size. Simil...
This video teaches you how to solve a linear system by mathematically graphing it out. The video starts off with a problem, asking to solve the system, with two given equations. To solve the system, one would insert 0 for x and solve for y in the first equation to obtain a point. Then one would insert 0 for y and solve for x at the second point. Afterwards, insert 1 for x and solve for y to obtain the third point. For the second equation, do the same thing, inserting 0 for x, 0 for y and 1 fo...
This is an educational site where we can learn about math lessons with example videos, interactive practice problems and can do self-test. The associate teacher in the video teaches us about fraction problems. She has written four numbers on the board, which is 1 1/4, 1 1/2, 1 3/4, and 2. She explains how to find the next three numbers following the same pattern. The teacher in the video tells that the key in solving the problem is to think of 1 1/2 as 1 2/4. Each number in the given problem ...
