Are you tired of solving all these simple maths “problems” that are flooding the Internet? Here is a bit more challenging problem.
However, fear not my friend! No University or advanced Maths skills are required. Just primary (elementary) Maths needed. Have fun!
Let’s begin with something really simple to warm up:
a = 1 and b = 1
Therefore, we can write this as:
a = b
Now, we can multiply both sides of equation with
a. This, as we know from algebra, doesn’t affect the result (i.e. both side are still equal):
a * a = a * b
we can also write this as
a squared, i.e.
a² = a * b
Next, we can subtract from both sides the same value. Let’s take away
a² - b² = (a * b) - b²
Left hand side of the equation is equal to:
(a — b) * (a + b) while the right hand side we can rewrite as
b * (a — b)
(a - b) * (a + b) = b * (a - b)
We are almost there. Let’s just divide equally both sides by
(a — b) which will leave:
a + b = b
Going back to Step 1 we know that
a = b and therefore:
b + b = b
which is the same as
2 * b = b
which if we reduce both sides by dividing
b will get us in the end:
2 = 1
Can you explain this!? Please leave a comment below but don’t spoil it for others.
