The denominator of a certain fraction was 147 greater than its numerator. What was the denominator of this fraction, if after the fraction was reduced it became ? We can assume the numerator is , then the denominator is , and we have the following equation: (1)   The following steps solve the equation: (2) […]

Yo peeps! Yeti here, explaining the steps of inequality solving. We shall start by examining the following problem: (1)   Our first step would be to make the expression equal to 5. We can then get the following equation: (2)   After solving, we can get that the . But if you remember, the original […]

Yo peeps, Yeti here, explaining the topic of speed, distance and time. Now, Yeti here is on a very tight schedule here and so this post shall be very short and basic. So, lets start with relationships. (1)   (2)   (3)   Now, we shall present you with a problem and guide you through […]

As the following picture shows, the slope of a straight line can be found by using the coordinates of two points and on the line as: (1)   A straight line consists of many points, and every point has an abscissa   and an ordinate . For a straight line there is an equation which […]

How can you make 51 by using 5, 6, 7, 8? It is impossible to make 51 by just using arithmetic operations like , but if more advanced operations are allowed, here is a solution: (1)   Here is the program I used to find the solution. One of my colleagues contributed even a fancy […]
